Twin Exhaust On Gtr

[96GTRman]

Has anyone? or

Doe's anyone ..

know if there would be an advantage to runnning twin exhausts straight from the turbo to the tailpipe. ( each getting their own cat and muffler )

and would it sound nice ?????/

it wont sound nice unless you hav a cross-over pipe.

Same as V8's setups.

other than that, 100's of people have done it.

I want it to purr like it does with standard exhaust, but gain some power.

will run them next to each other and ad a crossover later if it sounds crap.

Have a theory that the early turbo will create back pressure to the late turbo if the pipes are joined. Could be wrong, dont know too much about cars but would like to try it.

It will sound crap. There is no "if"

early turbo and late turbo? a RB26 isnt a sequentially turbo'd motor

[rev210]

appart from the extra weight and difficulty in getting decent size pipe diameters to fit it is going to allow more head room for flow potentially.

As for sound? who cares. The sound of power is an easy one to get used to. It will sound different to a single if it makes more power then it sounds better in my opinion. For those hung up on sound why not get rid of the turbo and go NA with a set of extractors (thats where your logic will end up).

Thanks for that, sounds like you saved me some greif, I allways thought they were identical turbos but someone recently told me they weren't. I thought they might be wrong cos i had never read anything like that.

cheers for the help!!

they are identical turbos mate, not sequentialy staged. Providing of course you own a GTR i suggest you run outside and have a look under the bonnet. or drive it. then tell us if you think it's sequential turbo or not.

I have an apexi twin n1 system and sounds very nice although coz its a single turbo gtr it merges to one pipe anyway up near the turbo.

oh yes! its a GTR, took it for a couple of hot laps around the block just to make sure, he he.

No i dont think they are sequential.

wish you could just throw one on to see what it sounds like.

How do you know it will sound crap??

[R31Nismoid]

umm because i dreamt about it.

Do you have one??

[R31Nismoid]

I will have a twin exhaust on my RB26 in approx 6-8 weeks should chrissy not get too expensive

And this is from a person who has done this just a little more than once...

cross-over to balance it or it does sound... yuk!

[Josh]

according to ylwgtr2 it sounded like a superbike

I don't think that sounds shit..

EDIT* Just read your edited post.

Guess you would know then..

well if you have to add a cross-over what exactly is the benefit to running a twin exhaust?

would one large pipe not do the same ?

[MELV]

run twin from the turbos into a twin entry and exit resonator then keep the twin to the back of the car with a twin entry/exit muffler on the rear.

who cares what it sounds like. u want it to flow

originally you said a twin system would sound crap.now you are getting one but it will only sound good with a balance pipe.I guess then type/placement/diameter/brand of mufflers/resonators/cats etc is irrelevant : "they will all all sound crap"
