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...

IMO Cannon muffler and de-cat pipe is all you need on a 3S-GE, the Headers are already somewhat long-4 into 2 into 1, And if you've ever seen FE headers, you'll see how damn good the 3S-GE headers are designed...

What I'm thinking of doing with my exhaust headers is heat wrapping them and doing away with the tin heat shield, This will keep your exhaust gasses hot in the pipes (the hotter the gas the faster it flows) aswell as doing a good job of reducing intake heat

The 5S-FE guys regain arseloads of power with full exhaust system tuning that us 3S-GE guys never lost in the first place.
