Hey, does anybody have Duel exhaust on there Xterras, cause i could onlt get a single pipe on mine? also Which one is louder and better for Xterras Flowmaster or Magnaflow? Also one more thing, Do air intakes really do a lot for your overall performance and sound of your engine or not?

Search dude, tons of info.

I'll do my best to summarize though. Yes some people have dual exhausts, but they are custom made by shops - there are no bolt-on duals. I don't know if a magnaflow or flowmaster is louder, I do think more people here have flowmasters.

I put an exhaust on first and it helped some, but when I added the intake really did make a big difference - I think it's a synergy thing (the two together do more than what each alone would do). It does make it louder, it did help power, it did help throttle response a lot, and the two together sound great. I've not noticed any mpg difference.

I'm interested as well about what kind of dual exhaust systems people are running...looking into one myself and I want to know what the best option is.

Anyone???

All you have to do dude is go get a Magnaflow or Flowmaster exhaust, take it to a custom exhaust shop in town, and then have them put on duals.

Now, if you want it to come straight out on the back, I don't know about 05' XTerras, but you would need to remove the spare on anything lower. The other option is to have the exhaust tips come out right behind the rear tires, but the spacing is tight. I have seen ONE XTerra where it had duals and the pipes came out right BEFORE the rear tires. Really up to you man.

I have a Flowmaster 40, 3 inch exhaust tip, 2.5" exhaust pipe, and it sounds loud and great.

So should I get a Flowmaster dual out muffler or just use two pipes coming out of the single out Flowmaster muffler?

If you are going to go ahead and do dual exhaust, I would recommend that. Also, keep in mind that the XTerra comes with the potential to do TRUE dual exhaust coming out of the engine. Take it to a shop that won't charge you for looking at it and ask them if they think they can do TRUE duals for you. Me personally, I think dual exhaust on the XTerra looks good, but mainly for show. If you are gonna be hopping rocks, it isn't practical as the piping might get damaged. However, if you just wanna hot rod it, then go ahead.

Oh, yeah, sorry I missed the point of the question. Do the dual-out Flowmaster if you are gonna do dual exhaust. I think (not 100% sure) that the dual exhaust allows for better air flow when doing dual exhaust as compared to just doing an H-pipe.

I'm not too concerned about power...the X is slow already and I don't think any exhaust is going to change that too much. I'm mainly interested in sound. Right now I have a 40 series delta flow single out and I just want something that's a bit louder and deeper, especially at idle so I'm curious if duals will improve that for me.

If you are keeping the same muffler I'm pretty sure its not gonna matter if you have 1 tailpipe or 2, its gonna sound the same. The Delta series was made 2 be a little quieter than the originals. Have you seen the new Flowmaster Super 40...its supposed to be louder than the original 40 on the outside, but quiter on the inside, just a thought.

In regards to the Nissan Xterra's exhaust, the worst part on it would have to the Y-pipe. Who ever is plaining on doing an exhaust install: It'd be smart if you cut out the y-pipe by either having a dual in muffler, and single out. Or simply having dual exhaust after the cats.

Out of all the efficiency loses that the exhaust produces on the engine, the Y-pipe (I believe) is the worst.

If you want a mixture of power increase and simplicity, then why not have a dual in muffler, and a single 3" exhaust. I'm going for dual glasspack

So what would be the best option purely sound? Loudness and a deep sound are what I'm going for.

How are you planning on running dual glasspacks?

me, yes I plan on doing alot of things, but I know that in the end I'll probably have some limitations holding me back. Yes I plan on running dual glasspacks(somehow), my reason? Purely to get as much power as I can outta the engine. But than again I also plan on running the smaller 2.3 pulley, and making a custom cold air intake. You guys can discuss the better flow rates that mufflers give off, but if you guys killed the y-pipe, and had a dual in exhaust and single out, you'd probably get the best performance increase off of that. In regards to exhaust sound, I haven't spent any time in that category.

If you do a custom anything on the exhuast, get the intake on there first. The place I went to said they can adjust tone to be sure I don't get that annoying snapping sound. My neighbor's F150 does it everytime, and I clench my teeth at the cheap and horrible sounding pipes he put on.
And from my searching, I would go to a custom shop, price is a bit better than bolt-on and you know it will work the way you want it to when they are done.

This is my experience here:

Went to a local muffler shop and told them what I wanted. They had the muffler and did a custom piping going from 2.25 inches to 2.5 inches in diameter. I would not suggest going to anything more than 2.5 inches since it would drop the low end torque even more. We all know the X could use more torque.

I'm using a Flowmaster 40 Original series and I love it. It's nice and deep when I drive and a nice mellow sound when at idle. You will never achieve the nice rumble of a big V8 no matter what exhaust you chose.

I have to note that if you are looking for sound some people have said that Glasspack was a lot better. I'm happy with what I have.

I'm running a Flowmaster 40 and get a deep tone, but not much sound at idle. Glasspacks are your best bet to make some noise.

I have a 03 X V6 and am looking to put an exhaust on it. I am having a little trouble deciding between Magna Flow and a Flow Master. Any recommendations?

Depends what you're looking for in sound. I have a Flowmaster 40 Original series because I prefer the louder, deeper sound that it generates. Adding the FIPK cold air intake just enhanced the rumble that my X gives off.

If you want, you can always have them test the sound of either the Flowmaster or Magnaflow inside the garage. Only thing is that the sound won't be accurate because it's unattached to the exhaust and if it's inside a garage, even the meekest muffler will sound loud.

But I vote Flowmaster 40 original. it makes my X sound like a beast.

Thanks for the input! ! ! I Kicked around the Flowmaster for a while but got the Magna Flow since I wasn't really looking for max sound. I upgraded to 2.5" pipes as well. It sounds great and noticed an increase in power immediately. I am also going to install the Volant Intake System in about a week or two!
