hi guys, sorry to bring up another exhaust thread.... but, on my st202, i have put a custom muffler/can on the end (for sound difference only i know) ive de-cat'd too, now rather than have a totally new custom exhaust, i was wondering if i'd be better off just having a 4-2-1 custom manifold made up and use it on the existing pipe.. how much power (if any) would i gain doing this?, or should i just go for the full custom? thanks in advance for any help...

OP - You should definetly use the search functions and also just look around in the appropriate sections but if you don't find what you are looking for feel free to post up - that's what this site is for. Also you or anyone can feel free to PM me if you have any questions you don't want to post - I spend a good portion of my day answering PMs that range form the simple to the very complex. I never tire of helping others if they want to learn more about their Celicas.
