Can i apply all other 3 upgrades to my p220 (valve springs ,big bore,camshaft) without applying ffe . I want to keep stock exhaust .
N will using these 3 with stock exhaust cause any effect on engine life . N how much performance loss will it cause over ffe ?
how much bhp gain can i expect with these 3 using stock exhaust ?


hehe
I will do it as soon as possible and will try to make out the changes in the exhaust note.
