I have bought a gt35r and a high mount manifold, Wanting to know what size exhaust to run.

ideally probs a 3.5

but your asking for a loud exhaust that the epa wont like very much.

3" should be enough for around 300kw =]

A properly built exhaust wont pose a problem like that at all in 3.5"

Wish I had your muffler shop. I have 3 & 1/2 all the way with 2 custom mufflers and a resonator and its still too damn loud (98 dec.) I cant run at lakeside raceway because of it. :thumbsup:

Ideally 3.5 inch turbo back.

Thats if youve got the space. I had to use a 3 inch dump, then go a 3.5 inch from the front pipe due to space restrictions in the engine bay between ABS and engine. Still made an easy 350rwkw (RB26) though.

im using a Gt35R on my GTR engine but ive done with a very small exhaust housing

its a ATP in house machined garrett exhaust housing

its basically a .78 divided exhaust housing taken from some other turbo machined to suit the GT35r core

im also using a custom twin scroll aka split pulse manifold to suit the exhaust housing

it also has a ATP anti surge compressor housing as well

engine is just waiting to be bolted back into the car B4 its tuned

ill post up the results once its finished

dump pipe is a 3inch

didnt want to go to big because its my daily

I run a GT35R ext gate and 0.63 rear .... 3.5" turbo back custom dump... metalcat, rest is a "Lavidia" (I think or something similar) exhaust that was already on the car from the cat back... proper mufflers etc... its only loud over 4K.... passes noise test...

Dump was made by my old tuner... only had to bend the aircon lines a little to make it all work ......

currently 306rwkw at 16psi.... full tune in a week or so, but I'm not expecting any flow issues... at 24-25psi

    • As somebody who works in the energy sector and lives in a subzero climate, i'm convinced EV's will never be the bulk of our transport.  EV battery and vehicle companies over here have been going bankrupt on a weekly basis the last year. 
    • With all the rust on those R32s, how can it even support all the extra weight requirements. Probably end up handling as well as a 1990s Ford Falcon Taxi.
    • Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.
    • Thanks for taking the time to post that ! If anything changes or happens please do update us. 
    • Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.
