Gawd, it's embarrasing to go back and read my old posts. I ended up buying a Supra exactly one week after after those posts. I have learned a lot since then!

Anyways Ryno, you got some very bad information from Supraforums. (That's why I often post 7M-related tech questions here--Supraforums is full of kids that don't know what they're talking about.) I added a complete 3" mandrel exhaust from the turbo to the tailpipe, which is rumored to net an increase of 68 hp. I believe it. I used to reach full stock boost (6.8 psi) at 2500 RPMs and now I can reach it by 2100 RPMs. In fact I can hit 10 psi at 2500 RPMs now, so my turbo lag was reduced substantially. The less backpressure you have the quicker the turbo will spool.

BTW, check out the stock downpipe versus my new one. Can you say "R E S T R I C T I V E ?"
