i think for stock engine.. stock piping is good enuff. change bullet / muffler / extractor (4-2-1) for better pick-up.
pls correct if im wrong B)

Piping size is more important, while bullet and muffler provide liitle back pressure and reduce the noise..correct me if i m wrong

eg9525,
I think 2.5" for ur car is too much if ur modification is minimal. Your car will not enjoy the low-mid torque. In short ur car will lose the G-force effect. My satria mivec is using a 2" piping wt GTI muffler coz i don like noisy exhaust. Its difficult to find a exhaust shop that knows how to match exhaust + engine.

In my opinion, out of 10 exhaust shops, only 3 knows what u want, the rest are only interested to sell u noise, bigger size and more noise.....

FYI, for 2 " piping, the internal diameter is 1.75".

i'm using Rimus 4-2-1, 1.8 wira piping (jus plug & plug, didn't change any bullet or center box), hotbits GTi muffler....

i'm driving 1.3 carb satria...
after i change these stuff, feel more powerful, fuel consumption decrese.... :blink:
i also dono why... when go 4 high RPM, respon better when around 5-6k...
last time very slow, macam "asma"...... :D
