if i were you,i will changed to special tuned header/xtractor first that suit your engine.the piping will stick to the ori.bigger piping not always better.regarding the muffler,i would just say the N1 will be better.

QUOTE(soulfly @ Oct 1 2006, 07:59 PM) zenden 4-2-1 = proton ori 4-2-1 but does the original proton extractor is quite short and a little bit less in term of its diameter,how come it is equall ? anyway is it true or not...a smooth gas flow in the exhaust system will help a smooth gear change ? |
