exhaust silencers Options

lol...calm down guys. i am in no way thinking about stuffing up my exhaust !

first of all, im going to verify that my WG isint rubbing my downpipe. there is a big chance that it is, and that is whats causing the creep issue. i have already verified that my boost controller, actuator rod, and turbo hoses are in good shape with no issues.

besides that, i am currently installing water/meth injection on the car. this will allow me to run more boost and be safer, and not have to worry about creeping a few psi past where i wanted to be.

however, i think the idea of a small restrictor that you can bolt in and out, is a great one. you could fine tune the diameter if your exhaust, untill you find the best balance of creep and performance. i mean, lets face it, i know 600hp supra guys that run 3in exhaust. i don't think a 2.75in one would hurt performance at all on a 3s.

You'll be fine. In my Supra all I had was a 3" downpipe from the original CT26 turbine housing (ported out) going to the 3.5" HKS GT-Spec and I got 533 RWHP out of it. 2.75" wouldn't do anything to the 3S. I even assume it would help it out somewhere in the powerband. When I had an NA A'PEXi N1 on my Celica (less than 2.5" ID), it was quieter and I felt that the turbo spooled faster and the car pulled in a very linear manner compared with the 2.5" Focuz, which made the car fall on its face in the low RPMs and then the turbo would spool up suddenly. I know it wasn't a placebo effect, because my friend noticed it also. It was a huge difference.

i found a good solution to my boost creep problem. i set the ebc to 16psi. it seems to hold that perfectly with no creep.

It's probably because it takes most of your exhaust gas to hit 16psi on that ct26
