go enlarge ur throttle body. +BHP and almost legal coz u cant get caught.Originally posted by dazzler:hi guys i wanted to change my exhaust of my mit lancer CS3.i went to a workshop n he told me its better to add in a 4-2-1 extractor too.i asked him y n he told me its better as it helps with e fuel consumption when i change my exhaust.exhaust is hot bits.told me extractor costs $200 plus....i kn its illegal to put extractor.he said when my car goes for servicing he will put back my org exhaust.i wanted to know if anyone has done this mod.is it worth it n performance wise is there any diff?i heard fc is also affected.anyway wat is a function of an extractor?tks for yr advise guys!
I believe operated exhaust muffler will be louder thus can pass inspection ???Originally posted by TRD_Sport_M:dun change xos.. just operated it will do!
