What is the highest power someone has laid down with a 70MM exhaust????
The fact that I may have to sell my T1R duals makes me want too

~12psi
~500hp Dynojet
~450hp Dyno Dynamics
I'm sure this is no where near the "highest" power
I love my exhaust...glad I didn't have to get rid of it!
I am the same way, absolutely in LOVE with my T1R
Just wondering when it becomes a restriction, obviously things like manifolds will play a much larger role in this but at some point it must become too restrictive.
Who else is boosted with a 70mm?

The turbine absorbs a lot of the sound energy already, so the HKS exhaust should be pretty quiet. Wastegates and BOV's that dump to atmosphere will make a lot of noise. To keep things quite, have the wastegate dump routed back into the exhaust before the mufflers; and have the BOV dump routed back into the line between air filter and turbo's compressor inlet.

If your goal is 400hp, keep the stock exhaust.
I have a log manifold, 3" downpipe, stock exhaust and 3" cutout where the cat used to be.
At 17lbs I made 410hp with the cutout closed & 490hp with it open.
When the cutout is closed the car sounds as if it's stock.
