Anyone see this on "2 Guys Garage" this past weekend, 2/15?

Looks like just what we all have been looking for. Check out their website...I'm getting one real soon as long as installation is easy for our local muffler guys...I'll check with them soon prior to ordering.

Aero-Turbine Website

Call me EXTREMELY skeptical...

I dunno... prices aren't that bad... if there was a guarantee of some type I'd check it out... you don't really have a lot to lose...

Well, they've officially pissed me off... I tried to call and got no answer, so I emailed them... it just came back as an udeliverable address... they suck...

This doesn't sound like a bad deal. If I knew about this before I installed my new Borla, I would try it, but the Borla has only been on there for a month now and I like it too much to swithch right now.

From the testimonials people are reporting a 3-4mpg increase in fuel. For the people who over the fuel the X uses, put this on and report to XOC. I bet everyone is dying to know.

Testimonials, huh?

Austinbrtndr is the coolest guy in the world! He is selling the biggest and best oceanfront property in Arizona! I would recommend everyone do business with him!

I can write those up all day long... give me a call when you start believing it and we can do some business...

I never said I believed the testimonial. I meant for someone to try it if they haven't gone for a muffler change (if they wanted to) and report back to XOC. I've seen many posts on here of people wondering how to increase mpg. If someone was seriously wanting to test it out then here's a product that may or may not do the trick.

**On a side note**
Hopefully your sarcasm wasn't meant to start an . I don't think the performance forum was meant for those.

DUDE!!! Chill OK? Bad hangover today?
I emailed them as well but mine was not returned as "undeliverable". I expect they are overwhelmed with calls and email after being on a nationwide show...I'll give them time to answer before I accuse them of anything/everything.

I would expect this new type of muffler could be given a chance to prove itself by a few at least until proven otherwise? If everyone acted like you are doing you would still be working on getting our fire started for the evening meal when myself and others return with the food we hunted down.

Yes, Mr Bartender....I just referred to you as one of cavematic man mentallity.

It might just take something out of the ordinary to get us +MPG & BHP. This is a newly patented invention so it just might be truly a blessing for us X owners that we have so desperately wanted/needed. Many have tried different snak-oils to increase MPG...Some have even installed a snorkle thinking it would help...Maybe, just Maybe this will do some good.

Take a thermodynamics class then report back your findings. :rolleyes:

I doubt that "patented" technology can override the laws of physics...

There is also a reason that car manufacturers don't put these things in their vehicles. If a muffler could increase your efficiency 3-4 mpg some manufacturer (with better test equipment and better engineers) would have bought the patent rights. This is similiar to that goofy intake swirly device that was touted for a while.

Try it if you like, I'll save the $$$ for a lift.

As always YMMV.

Dang... sorry guys... I was just joking around... knew I screwed up when I forgot to add smileys... :p Like I said, it doesn't look like a bad deal... If I had the extra $$$ and they would give me some type of guarantee I would go for it... Definitely not trying to start any arguments or anything... I'll leave that for Brent!

No kidding! It's amazing the kind of BS people try to sell. I've got an ME and Aero degree and this product is bogus. It's just like any other after market exhaust out there except it's got a sexy looking "accelerator" in the exhaust flow. What cracks me up is that they have the audacity to show "data" that shows that their product produces a WHOPPING 1-2 Hp over stock on relatively large engines. big deal!

No disrespect meant to anyone in this forum that was looking into buying one of these products.

Can't imagine what the heck has gotten the RX7XTERRA guy so upset and a Dr might be able to help you with your vommiting? Thermodynamics I did 20 yrs ago and is not at all my discipline yet I did quite well in the classes and have a good understanding. I could care less about any temperature +/- related to this NEW device, As the subject of this now extremely argumentative thread states, +MPG & HP are my targets and many others here. Take your college boy BS to the restroom and re-insert it back to where it came from.
Personally I cannot understand why people install lifts when you can't change the height of your differentials????? Seems to be snake oil many buy into.

I called the closest shop per their website (~120 miles away)and got a quote of $250 installed. The shop owner is familiar with XTERRAs but has not yet installed one of these on one so I could not get any vehicle specific impressions.

ALSO... I received an email from the Mfg quoting here:
"You simply need 1 at-2525 aeroturbine. Thanks should be all that you need.

The total is $192 and we are offering free shipping.

Please let me know if you have any questions.

Thank you,
Tony @#$^%^"

Man, I just came in here offering hope for an extremely popular concern and get shot down by a bunch of pricks.

It just might be really nice to sit down with some of you guys and see what you are really made of...Oh but you have proved that now haven't you?

As I've stated many times, the first stage of learning about something new is typically to laugh at it and then, after investigation it soon becomes an obvious fact.

It's not built like any muffler I've ever seen? Name one similar please.

I don't recall vomiting lately, just hoping to save you from buying something that won't work. Sorry you thought this was an attack on you or your opinions. I just think it is funny that people "invent" and patent new technology with fancy marketing words. First law of everything would be "if it seems to good to be true, it probably is."

BTW thermodynamics is not just temperature changes, but energy changes... just FYI.

I don't want to really get into an internet arguement we all know what winnning those is like... :p

I'd be more than happy to sit down with you anytime I'm in the neighborhood. I'd guess you'd be alright especially since you have an interest in the Xterra as I do. Sorry you think I'm a prick.

Bernulli's equation ring a bell with any one? A Everything else being equal, when velocity increases pressure will drop. In this case increasing the velocity through the exhaust causes a decrease in backpressure. Same effect can be done with a larger exhaust. I'd be curious if they go to a larger diameter exhaust when they mount this. I think it's just a marketing gimmick, the only benefit is a less restrictive muffler (maybe)

PS...OH, and by the way, I'm a designer/inventor of some 24yrs professional experience of which I have participated in the invention and patenting of many ideas and products that are used the world over everyday. Many have laughed at me in the past and I hope it continues.

RX7XTERRA.... Apparently you find yourself qualified to teach me basic engineering fundamentals. I've already stated to you I'm fairly familar with the academics of thermodynamics and then some.

I just posted this info on a NEW product that MIGHT help us and you come guns a blazing shooting at anything that might move.

Maybe you will think about your behavior and apparently closed mind a moment and realize you might not know everything yet? Maybe you can still grow a little?

Being an educated moron still means you're a moron. Dude, as soon as you justify your stand with "I'm a experienced asshole in this field ..." you've lost the argument. Show some facts that aren't provided by the marketing department of the thing you're trying to defend.

Alert...Alert... Prick Attack More guns a blazing. Go away Steve.

I think the basic gist of this argument stems from bonestx's feeling that new ideas should not be immediatly shot down when they have not been thoroughly looked at by those doing the shooting... I agree with him (I do not appreciate the attack on college education personally).

The thoughts that Aero Steve and the other dude are expressing seem to say that they have the background and education to be able to disprove this new "technology" by reading the website claims. This point also seems valid at first glance and it occured to me that the claims made seemed impossible for this passive device.

You both have points but which one of you doesn't want to see it tested out and reported on by an unbiased person?

The design makes sense, so does the logic. In looking at the performance gains, I can get the same buying a Flowmaster and going to 3" dia. piping. In a V6 (Accord) there was only a 3 HP and 2 lb./ft. gain. Not enough to spend an extra $100 on a muffler. Good call on showing a new product, but not enough performance gains to buy.
Last time I checked, 3 hp/ 2 lb/ft of torque was not a larger gain than slapping on free flow headers/ exhaust. MPG gains look to be exaggerated.

Unusually I agree with you this time, it does appear to be an extreme MPG gain. That is the only thing that caught my eye about this muffler. After looking further into it it does sound good also, not so "whiney" or "RICEY" in my opinion. The FORD truck done on the show sounded cool as well.

Personally I don't need additional HP or torque, I find it to be quite sufficient for my needs as is but the MPG leaves a lot to desire. If I didn't like the X's HP and Torque I would not own an X, I'd still be in a FORD or???(What a great quality vehicle...NOT!).

OH NO....Have I inadvertently started another MPG thread.....Please No, let's not get into all that.

I agree about the Bernoulli's equation and that the increase in velocity will decrease the pressure. My only doubt is that putting anything in the exhaust path can reduce backpressure compared to an open exhaust. You gain low-end torque by increasing back-pressure, so the claim of more HP (versus open exhaust) has some validity.

I guess my whole gripe with the product was the marketing spin that this muffler has less back-pressure than an open exhaust... Seems fishy to me.

I didn't think any of my posts seemed inflamatory or insulting/degrading. I don't get why everyone gets in such a huff when someone else writes a post with a differing view. Never once did I say I need to teach you engineering fundamentals or claim that anyone that patents anything is always worng.

It seems to me that, bonesnTX, you are the one that is attacking my and Steve's original post. Sorry you got a negative view. I guess that's what happens when you post things on the internet.

It really depends on who/what is reading info on the internet as to what will be understood. You and Steve's posts are extremely demeaning and I'm not the only one that feels this way...Others are sure to follow still. Thank God at my age I have a more open mind than I used to.

The damn design....AGAIN...If you would read how it works and IF you would have seen the show explains very simply that back pressure is obtained via the holes on the O.D. of this stupid, Damn snake oil muffler. It really doesn't have to be even half as complicated as the deep end you so gleefully jumped into and are still sinking into.

It never ceases to amaze me how easily some can and will say something will not work. All the smart guys in a row.

I'll remain skeptical. Bones, you get 3 baseline dyno pulls before, and another 3 after and document your mileage before and after. If there's an improvement worth noting, I'll change my position. I ain't gonna bite on the placebo effect alone, a wallet $189 lighter does make a "seat of the pants" difference

From what I remember from aeronautics.. Subsonic airflow: increase the crossection, and the flow rate drops.. decrease the crossection, and it increases.. Supersonic flow, is reversed.. unless your exhaust is moving one hell of a lot faster then mine, a larger exhaust will only lower the velocity.. The larger exhaust will lower back pressure, to a point, you get to large, and you loose the scavengeing from one cylinder to another..

Hmm... Maybe that is the "physics" behind the scavenge effect.

Dyno testing will not be available to me as I live in a complete lack of money these days after being laid-off in 1999 and acquiring another job that pays much less but has other advantages to almost make it tolerable.

I'm after better MPG, that I can track as I have tracked my current, stock configuration from the beginning of my ownership bought new in 2002. That I will publish here extensively and conclusively. The stock torque and HP is fine for my needs but I know others have complained that the X is not sufficient...I've never had any brand of truck leave me at a light if I cared at the time. No, it's not quick or fast but for that we should be driving old Hot Rods, Ferrari or one of the new wizz-bang supercharged cars.

Yes, increased volume decreases velocity (deceleration). But they claim acclerating exhaust gasses. The reason they are right: Rotation. The Exhaust rotating is technically constantly accelerating (in an new direction). So that claim is true. BUUUUUT, that kind of roational acceleration does nothing for reducing pressure or increasing flow upstream.

It's all a gimmic.
Here's one for you, stop buying cheap gas, buy the "super" and you'll gain more HP than this bogus muffler. Hmf! :rolleyes:

I have some snake oil gas additive. It's only $50 bucks for one bottle, and it'll last you 5 years.

Mech. Engineer. CA.

Rotational acceleration?? True, a change of direction is an accelleration but comes at the expense of linear velocity... energy has to come from somewhere so you must therefore have created more backpressure...

I hope you were kidding about higher octane gasolines.

Well, he is a mechanical engineer...

Some of the biggest idiots I've encountered have degrees. If they had not acheived a degree they would not be capable of making it at a McDonalds type of brainless work. College was certainly nothing difficult to me...You should see some of the quacks down my halls...!

Hands-On experience is what makes someone's opinion maybe worthwhile...An educated person with hands-on experience at times is even better.

All bickering aside, aren't the HP and mileage gains these gizmos claim to achieve only attainable at a constant full throttle for an extended period of time?

I saw some show on speed vision where they did some basic research into these kinds of products and said yes, they can claim certain gains, but only in non-realistic (i.e. racing type) driving situations. You'd have to be going a constant 90 mph for a prolonged period of time to see even a minimal gain. And they said some products may work on older carb engines, but not on todays FI type engines.

Just 2 cents worth....resume bickering....

Until someone gets one, tests it and reports data all that is available on XOC is BS based on BS OPINIONS. Then, when someone does report findings it will be laughed at, dis-credited as "in-error" or "you don't know what you are talking about".

Right off the bat, the hungover bartender discredited the manufacturer stating he could not get email contact or phone contact with them and unfortunately his drunken comments wil probably be remembered for a long time. No matter what I say after my analysis, the drunken comments will prevail?

Funny how easy it has been for me to converse with them?

After checking out the website, I can see how a very minimal gain might be possible. The goal is to increase airflow through the system. Hasn't K & N has been doing this for 45 years? Don't they make similar claims: MPG, torque, and HP? Last time I checked, K & N had a very good reputation for a product that does exactly what this one claims.

I don't see how people can be so convinced it doesn't work if they've never tried it. As far as I know we're all just going off opinions at this point, right? Are there any X owners out there that have this? Any unbiased data? Any before and after benchmarks?

Does everyone feel better now? That was pretty fun.

Bizarre........
Why such a big fight?

The scientists are right!

The second law of thermodynamics doesn't cease to apply........

The reason a supercharger works is because it forces air through the system. A K&N works because it decreases the amount resistance for the air going through, thereby increasing airflow. A performance exhaust system works because it allows increased airflow (more room).

A high-flow muffler on a stock exhaust will work to a certain extent.........

But this product does not do what it claims.

It probably just functions like a glass pack, which I can buy at Autozone for 20 bucks.

Ugh, just when we thought this stupid thread was dead...

I know this thread is super old but... I bought The aero turbine for my 2004 v10 excursion, and all I can say is wow! I was getting 17-18 mpg on two seperate long distance trips at 70mph and I did get an increase of tq/hp. I don't know how much it went up but I could definitely feel the difference. I also liked how quiet my truck idled, until I put the foot on the pedal, thats when the v10 purrrs like a pissed off lion! Definitely the real deal. I did add a new y-pipe after this as well, hell yeah, great improvements. I plan on adding this to my 2013 xterra S 4wd. To me, its all in the exhaust and gear ratio.

You are misperceiving the performance change due to the aero crap.

Its a common issue, so don't feel bad. Many many people are fooled by their need to justify efforts, and therefore interpret sensory input in such a way as to reinforce what they need to feel.

I'm not sure what you mean by "it's" in your sentence regarding the exhaust and gear ratio.

As in if you are accurate, you don't need to take in any air, or, burn it, or have a way to transfer torque from the engine to the transmission, or from the transmission to the diffs...just have a good exhaust and gear ratio.

As I believe you do need those things too, we might disagree, or, we might agree if we both knew what you meant by "it's".

If by "it's" you meant something besides what it sounds like, perhaps something that is actually the case, sure, that's possible.

Or you're just spamming.

Etc.
