'Proper' dual exhaust setup on V6

[JetspeedCamry]

I was just wondering, what sorta gains there could be, by making a dual pipe setup on the V6. This would mean that the front bank and rear bank would not converge into a Y pipe, and would travel down the length of the car, one going to one side of the wheel tub and the other to the other side, or both to one side into a dual inlet muffler. Obviously, sorting out resonators, flexpipes and cat's would be an issue, but im sure something can be done. Anyone have any idea what differences it could make? The piping would be maybe, 2"/1.5" for each pipe, give a total of 3-4" from a normal single pipe.

Thanks

probably nothing

our v6 fires evenly so pusling woudlnt be a problem but erm... exhasut mods dont do too much for us :P

well maybe your 2vz with its drink straw headers but...

id say 2" all the way....

Yeah, it would seem the 2VZ headers are one of the worst! Seeming they never ued that design again on any other V6 :P Thats where i got my biggest gain. I also feel large gains from larger piping and the straighthru muffler. Putting my old one back on once, made alot of loss.

Just wondering opinions on the whole thing. How about sound? Would the turbulence in the Y pipe cause any loss? Having individual exh. banks would eliminate the convergance of the two.

yaknow what a 3 cylinder sounds like, right? :P

either way you would want them to converge at some point. It would probably sound like crap unless you had really good mufflers. I have heard a couple of the Dodge Ram rucks with the V10. They ran them straight out with no crossover and they sounded like crap. Basically two 5cyl engines running. But as soon as you put the crossover pipe in it it sounds so much better. If you look at most vehicles that run a true dual exhaust they meet somewhere under the car to even out the flow and it also helps with the sound.

Y, without a Y pipe it would sound like a 3 cylander lol, which could also be called hmm... Maybe a dodge neon or 88 crx with the muffler cut out and a can in its place... Get a Y pipe made for your exhaust, youll be happy for sure man!

LOL.

I have a Y pipe....i have a V6....

In any case, yeah it makes sense that with some sort of transfer pipe, it evens out the sound. I guess that means that there would be no performance benefit!? Mucking around on a V8, we experimented on T, X and No cross pipes, and all had different sounds...but none sounded bad. Having no transfer pipe on the V8 sounded quite good actually, more "lumpy". The T pipe tended to make it sound more fluffy.

Anyhoo..just a thought.

your best bet, if you haven't already done so, is to get a well designed y-pipe w/ bigger piping and designed to minimize turbulence

I'm not sure if the 2vz stock y-pipe is as restrictive as the 1mz, but if it is, you should get some noticable gains from that

[terrastrife]

jetspeeds got the whole hog already, headers, secondaries, cat back, a/f tuned.

[JetspeedCamry]

^ Yeah haha....im not asking "what" i should do to improve performance....im just asking opionions about if such a mod was done.

[Eye8Pussies]

ah...I see....



then I'd just say....why don't you try it and tell us how it goes?

Thanks

single 3 in = 7.067 cross sectional area
dual 2 in = 3.14 + 3.14 = 6.28 cross sectional area

7+ in is a lot of pipe. Enough for just about any power you can get from a camry
