yeh?
im not sure wat exhaust i got, i think its a catback 2,1/4 as weo coz im sure its a stock headers for sure and some saas? pod air intake filter.

thing is i couldnt find many camshaft for this engine and even if i do custom make a bigger cam does it require an aftermarket ecu? how about hc pistons does it have to work with a new crank? i think cams, pistons would probably gain at least 15kw? hrmm mayb the question is if its worth the money.

anyway anymore suggestions?
thanks guys
