Who has a flowmaster? What kind? How do you like it? Was it what you expected? How's the performance? Was there a difference in mpg, horsepower, and torque. I don't need to ask for the sound quality because it's a Flowmaster. Im going to get the 50 Series SUV Muffler. Does anyone have this one? Hope to hear back from you all on your Flowmasters.

There have been a bunch of threads about this already (including 2 right below this post). You can do a search for "Flowmaster" and come up with a ton of information on opinions, difference between 40 and 50 series, size, model #'s, etc. Here's a few links to get you started. Hope this helps.

Currently I have a Flowmaster 40 Series on my X. The exhuast has a nice throaty sound to it but even under acceleration its not "too loud". Now while exhaust tone is a subjective topic, I think you'll be happy w/ either a 50 series or a 40 series. The only difference between the two, I believe, is that the 50 series is a "quieter" muffler. Let's just say its a more conservative approach to the Flowmaster sound. Performance gains exist but the real gains will be if you totally replace the exhaust pipe to a slightly larger diameter w/o loosing too much backpressure.

Hope this helps a bit. . .the above links should give you some other view points as well.

like it has a 2.25 on the pipes right now i would get a 2.50 said one mechanic at Midas. That is not that big of difference in diameter like u had said. 2.50 would be nice but do u think it would mess up the back pressure on the engine. And i would get aluminized pipes not stainless steal too much in price.

Dude you don't want back pressure. The faster you can get the exhaust out of the car the faster you can get air in the car. The bigger pipes will be fine.

Currently I have a Flowmaster 40 Series on my X. The exhuast has a nice throaty sound to it but even under acceleration its not "too loud".
Its just right for my taste.......and since its not loud at idle, its perfect for my remote start, since it wont bother my neighbors.........

Did you get the 40 Series Standard or Super 40 Series muffler. Why didn't you get the 50 Series SUV which is designed for V-6 engines and SUV's. The master mechanic from Flowmaster said to get the 50 Series SUV and not to get bigger pipes on a stock engine because it cause mess up the back pressure. I think the 40 Series is too loud froem what I here and I live in a complex with a whole bunch of old people and want an exhaust that had some nice sound but not to loud that would be noticed too much. Yet I do want the 40 Series but also want the 50 Series SUV because it is specifically made for SUV as to the 40 Series made for Street Cars not SUV's.

I have both. I had the Super 40 on my X for about 100 miles and decided that it was to loud for my taste and my neighbors kind of hinted that point as well. So I switched to the 50 SUV and I love that thing. Nice deep sound but not to overpowering as the 40 series. At idle it has a little rumble, but you notice it when you accelerate.

I have changed my mind and desided to go with the Super 40 Series Muffler. I spoke to the master mechanic again and said not to go with the Original 40 Series but to go with the Super 40 Series with Delta Flow. The Super 40 Series has a the same of both worlds Sound and Performance. Plus it has the least amount of interior resistence which is good in my case. I want the loudness now. HAHAHA

interior resistance? as in, it's loud inside your car?

i am also about to modify my pipes. was thinking the flowmaster 40 delta.. but i don't want it to bother me and my music listening.

It doesnt interfere with my music.....do you have stock speakers of aftermarket?
I have 4 aftermarket speakers running of a 4 channel amp tho, so I dont know if it would be any different with the stock system.......

I got the Super 40 Series Delta.......I got it for a good price from someone who got rid of their X before he got a chance to install it.......

Robb

nah dude. they're factory. but they're the ones that come with that rockford fosgate system.

i used to be into making my civic's system uber pimp... but i assure you, this system is no push over.

regardless, i have 0 experience with aftermarket mufflers. so i just wanted to find out if it would be annoying at all... or kinda like that logic behind getting a tattoo. *sometimes you're glad you got it, and most of the time you're not*

That should be fine (Fosgate).......
and my stereo setup is nothing crazy, I used to do all of that stuff in my last car........I just wanted something nice and full sounding, the stock one sounded crappy to me (flat)......

Robb

W/ re to backpressure. . .the larger you go w/ the diameter of the exhaust pipe the more you increase your top end and the more you increase your low end. Backpressure helps greatly w/ your 0-60 performance while a larger diameter pipe help w/ lets say your 'cruising' speeds. I have had technicians tell me that a 2.5" pipe is probably the largest one should go on our 3.3L engine set-ups. A larger pipe diameter is more at home on a big block V8. The interior resonance of my 40 Series is not as bad as I thought it might be. Under hard acceleration its quite evident but under cruising speeds its not very noticeable. My current exhaust pipe is a 2.25" so w/ a 2.5" pipe it might be a bit louder.

Hope this helps a bit.

Very well put..I would not go bigger than 2.50" with our engines.SC'd models although might take bigger pipes.Anything that is running turbo or supercharger will benefeit from a larger diameter pipe..

I'm running a Flowmaster 50 series single in dual out to the rear using 2.25" pipes and it sounds awesome..

Well, the 40 Series Flowmaster (which is what I have) is not loud at all. You can't really hear it that much when idling and you don't have to mash to the floor when leaving your apt. complex. My neighbors sure are fine with it. I would say that the Flowmaster 40 Original sounds more like the Infinity FX or the G35 exhaust. Ever heard that sound? Nice and mellow yet with a little grunt.

40 series Delta is quieter and 50 series SUV is also quieter than the 40 Original.

I love my 40 Original, that's all I gotta say.

The Super 40 with Delta Flow is better in the inside of your car because it will not be as loud compared to the Original 40 Series. Plus it sounds the same on the outside and you really dont need to hear it in the inside unless racing with manual but then why are you racing in an X-Terra?

Well, it actually is a little quieter on the outside, that's why you don't hear it that much on the outside. It eliminates the tone that's amplified inside the truck, but sacrifices outside sound. After all, sound does not care what is in it's way. How can it be the same on the outside yet quieter on the inside if nothing was done to the X????

main question is what about the new 05 xterras?

they have bigger engines. would those larger pipes be appropriate on ours? or should i stick to the 2.5's or under still?

also, as far as the noise argument... it has to do with depth or high end noise quality. if it were full of depth, it would carry through the interior of the car way better. if it were high end noise, then it would also. but if it weren't extreme on either end of those frequencies, then it may not be so loud on the inside, but still seem really loud on the outside.

either way, the bottom line is what the decibel is.

I have an original 40 and 2.5" piping and in no way does it sound like a g35 or an FX. An FX45 has got a v8 in it and no matter what you do to our engines it's not gonna sound like a v8. I've driven my buddies g35 coupe and it's quiet not loud at all. I think i'm going to go with a delta series or maybe the 50 cuz the sound is getting old to me. At first i liked it, but now i wish i would have gone with a delta flow, but it's all personal preference

Sounded like it to me when my g/f it too much. drove it. Maybe I just like that sound way too much.

Do any of you guys have or can make a sound clip of your new muffler? I would really appreciate it.

I'll try to make one today, I planned on making one anyway. Check back this evening.

Here's a sound clip that you requested. I have one more clip of sound under acceleration. IF I can shrink it I'll post it as well.

wow thanks alot. I really apreciate this and if anyone else out there with the Super 40 Series Muffler could make a sound clip that would be great. Or it anyone else with a Original 40 Series.

Here's a video of my 50 series exhaust.I'm running the single in and dual out (to the rear) 50 series.

This is a stop to take off video.

On a side note RI Xterra did i see you registered in the photography on the net forums?

You talking about the canon one?if so I sure am.

Very nicely done. From the movies it sounded like a 4 cylinder Honda Civic but it could be the camera because the X-Terra's are a BEAST not a rice burner. But sounds nice and can't wait to get my Super 40 Series. Also if there is anyone else out there with a Super 40 Series please make a sound clip or video. Or anyone else with a Flowmaster.

By all means the exhaust doesn't sound like a Honda at all...It's a really deep mellow tone and not a raspy,coffee can rattling sound that you hear on 95% of the Honda's out there.. :rolleyes:

Probably listened on a PC with poor speakers. The one I posted sounds like Jap fart can as well becasue the speakers on work computer suck ass.

Yes that is it because i have crappy speakers on a brand new Compaq Pentium 4 computer and forgot new speaker'. So my bad it doesn't sound like a honda civic.

Yep, i just got a rebel XT and was browsing the forums for some tips. I got a steal on the camera is the only reason i bought it. I'm a noob to SLR and never had any interest in paying 1000 for a camera, but I could not pass at the price i got it for.

I have a Canon G6 that I got for nothing (gift) I also have a G3..But I wanna buy a SLR.I was thinking of either getting the XT like you have or go with a 20D..

How do you like the XT?

Why are we talking about a digital camera?

It's what I used for the video...

OOOOOOO Cool.

From Flowmaster:

Standard 40 Series - Two Chamber Mufflers
This is the most “aggressive” sounding street/strip muffler that Flowmaster offers. If you're looking for attention, this one will get you noticed. The standard 40 series has an “aggressive rumble" and will generally resonate inside the vehicle around 1800-2000 rpm’s, and again at 2400-2600 rpm’s. Constructed of 16 gauge aluminized steel and fully mig-welded for maximum durability

Super 40 - Two Chamber High Performance Mufflers
The Super 40 is our latest development utilizing "Gen II Delta Flow" technology. This gets you the best of both worlds of Sound and Performance. The Super 40 has that "deep powerful" sound of the original 40 series but with all the benefits of performance and low interior resonance from the "Delta Flow technology."

40 Series Delta Flow -Two Chamber Mufflers
This two chamber design incorporates Flowmasters patented "Delta Flow" technology. The "Delta" deflectors result in increased scavenging for better performance and reduced interior resonance over the standard 40 series with a nice growl outside the vehicle. Sounds great on late model performance cars with catalytic converters. Constructed of 16 gauge aluminized steel and fully mig-welded for maximum durability.

Now out of those three top mufflers from Flowmaster I would think the Super 40 is better right because the Super 40 with Delta Flow is less power but pretty much the same sound as Super 40. But the 40 Series is all sound "aggressive" sound that is. But in it's paragraph it states for Offroad and Street use i think. The others don't. Im sure you can use them both Offroad but im starting to believe that 40 Series is the best bet. But I do like that the Super 40 Series has the "Best of Both Worlds" Performance and Sound and that the muffler has the classic black coating on the outside. Which do you think guys is really my best bet if im going with just a new muffler and keeping the catalitic conveter on the car out of those mufflers?

Thanks,
Nick

Getting my flowmaster 40 installed in the morning. Can't wait. But just wondering...does anyone else find that theres alot of moisture coming from the exhaust? I know that on cold start ups, my exhaust drips alot!! So I'm wondering if I should drill a drain hole in the bottom, to keep it from rusting out on me. Anyone?

Yeah, there's a lot of condesation but it's normal. I actually have had a hole in my Flowmaster so when condensation forms it drips out of the muffler as well. Most mufflers come drilled so that they would not rust from the inside out. You can always enlage that hole a little.

Yeah so I got the flowmaster installed today. And to anyone who's afraid to put one on because its too loud.....don't worry. Its not!! I love it, and it does sound better. But to be completely honest, I was alittle disapointed that it wasn't much difference then the stock system. It does sound better, but you mostly just notice it at between 2000-3500 rpm's. On the highway you can't tell any difference at all. Still cool tho.

What type of flowmaster?

You can surely tell the difference with the 40 series original. I have a nice low rumble in the cabin pretty much all the tiem from mine.

Keep in mind that with tiem it will get louder once the Carbon and other deposits will start forming.

I got the 40 series original street strip

Flowmaster 40 Series Delta Flow for me.

Heard some of the same stuff
been going to the same muffler place for years and have always liked the 50 series flowmaster which is what i just put on my 05 along w/ the K&N FIPK
AWESOME, love it
from what i what told the design of the 40 vs. 50 series and why the 40 is louder, don't know if there is a pic online but at this shop and maybe one nearest u if u look at one of them cut in half u can see that the 40 series is a what they call a two chamber and the 50 is a 3 chamber from what i have been told
heard the 3 chamber creates better performance gains and the sound is deeper
i would get only a 50 not a 40

40 Series Delta Flow cut in half.

I have 40 and i love it..........

Have you seen a noticable difference in performance?

Also, I'm really curious about the sound...any way you could put up a sound clip (or anyone else with an 05 for that matter)? I had a Flowmaster 40 on my 04 but I'm really wondering what it would sound like on my 05.

The same...different?

you want a little backpressure unless you are insane for RPM (not with the 3.3L) 2.5" exhaust is too big for the X unless you are running single exit pipe on the SC or with a turbo. 2.25" is perfect for the NA engine for maintaining torque. I run a 40 series because i like the noise, and the fact that "loud pipes save lives" no jackass in their right mind would pull into your lane if they could hear you coming! if they did i'd just ram them!

http://www.xterraownersclub.com/forums.html

I have heard a few people say that U cant run dual exhaust on a Xterra. IS that true? I assume there would we too much back pressure or something. I just wanted to here if it can be done safley, cause i wanna run dual flowmaster 40's with 2.5 in. pipes.

duals are possible with a good exhaust shop to do it. 2" is all that is needed to run duals, and if you want the look then run 2.5 for the last 1.5 to 2' of pipe you don't want to run 2.5" because you will lose all performance and a ton on fuel mileage. a crossover pipe will help the balance between the 2 sides of theengine and might actually work for your benefit. I bought pre-bent pipe and took my X to work to do the pipes myself, but your better off finding an exhaust shop to do it for you.

sounds like will just stick with my 2.5 in single outlet Maganaflow. I mean it is an Xterra and not like a V8 or a hemi or something like that.

I have duals on my X..It's very possible..Yeah sure it's not a V8 but with the duals and the Flowmaster 50 series it's sounds really good..

NICE NICE!!!!!!!!!

Wat size pipes u running, i am afraid to run 2.5's on a dual, i was thinking about doing 2.25

I went with 2.25" pipping..

RI Xterra: that setup you have looks deadly! what exactly do you have for piping? Is it just a catback setup? or does it go all the way to the header?

ITs illegal to remove the Catylitic Converter, at least in VA it is. DUnno about anywhere else. and how the hell could u tell if u was running strait pipes by just looking at the picture, u would have to look under the car, no offense, just wandering how u came up with that observation.

OOOPS, sry, didnt read completely what u were saying, TIME TO GO TO BED!!, no wander

That's just a cat-back...

If someone actually made a set of headers for our rigs then I would have gone with true duals..

SLR has a set of headers. I'm currently putting them on my truck. And I must say, they are DAMN good looking headers, too.

Whatever problems they used to have w/ 'em, they definately don't anymore.

So now you can go w/ true duals...

---I just put Flowmasters 50 series (offset model) on my '06mt off-road and used all flex brackets and stainless (1 ft) tips all welded. the sound is very pleasing and has GOOD raps-- JIMBO
