Hi
i dont know whether to post it here for performance or in 4g63 section. I have a GST and was wondering what the HP gains would be with just the catback system..not the whole downpipe race pipe..is there even a gain? I know more air flow in exhaust helps my turbo spool faster but it's just a T-25 so it should spool up fast anyways. Just curious if the N1 gives any gains that you can feel. I just bought one..getting it in 3 or 4 days. Just wondering if when I hook it up if I can feel it or not.

I say about tree fiddy

actually to be honest I'm not really sure I know a full 3" turboback exhaust with a test pipe will prolly net close to 30 (don't quote me on that) so I'm assuming if your just gonna do 3" N1 catback maybe like 10 or so but that's just a guess don't take it to heart

you should know that an exhaust is a turbo's best friend...for turbo cars exhaust make a difference you can feel, where you really can't feel it on non turbos.
