I am going to run a 4" downpipe and exhaust off my one-fab top mount with the gt35r.

I was originally going to go with just a turndown at the rear bumper but now I am undesided.

There is the Dynomax Ultra Flo http://store.summitracing.com/...w=sku (Aluminized)

Then the Magnaflow Race Series http://store.summitracing.com/...w=sku (Stainless)

Should I add in one of these aswell to help reduce some of the bad sounds http://store.summitracing.com/...w=sku

Tip? http://cgi.ebay.com/ebaymotors...&rd=1 What one? Think it will fit with the muffler aswell?

Now what would you guys suggest for what comes out the bumper? Just the end of the muffler? Tip? turndown?


Now I want to re route my Tial 44mm back into the downpipe as I do not like to smell my exhaust when im driving around. Matt @ one-fab does not want to route my dump tube back into my exhaust as he says it will cause many problems (fitting, warping...) aswell as it cancels out the point of having 4" (Now with a 4" exhaust and a goal of 450 pump, 550-600whp c16 I would think there would be room in that 4" exhaust to flow the wastegate gasses aswell) give me your advice, I am goind 4" - that is not changing.


Does anyone have 4" flex's in stock? Also has anyone seen a 1 5/8" flex?


Thank you
Kyle

 

alex from neukin made some crazy closed dump exhausts where he said the exhaust actually creates vaccuum and sucks the gasses back in, so there is nothing to "inhibit, or mess" with the original exhaust flow. i think im going closed loop also. and it's decided.

 

Magnaflow has everything. So you dont need to mix and match.

Resonator is a muffler.

Stainless is better than aluminized.

 

i ran my closed loop to begin w/ on my 3" dp just go far downstream 18" or more preferably....we also modified my friends prelude's current dumptupe to reciculate also to help him quite it down a bit...open dumptube is loud for some people going for the sleeper look...also helps keep people from staring when the tires tart breakin looose...heh

but open 3" dp is to eat little kiddes...mmm their yummie

 

i would do 4" aluminum...is what i am doing for my street/ drag car.

just have 2 chips burned ....1 for open dp and one for full exhaust.running full exhaust will take away some,but nothing that will slow the car down dramatically.yes your car will be quiter,if you close loop....but i would also add a resonator,then a muffler at the end.so you can ride around in peace....but also when you go to have your exhaust made....make it in sections so it doesn't take long to get it off and have some fun at the track.


my 4" aluminum exhaust will be v-band,don't worry i will have pics up when car starts coming together.
