Hi all sifu sifu here. Newbie here. Just got my lovely neo cps last month.
Love the handling and the shape.fun car.
Currently planning to change the exhaust system . But dunno go for which extractor .
Need some advice from yours. Any suggestion???
:wavey:
u bought your car new? by modding on those parts could void your warranty.

Why not go for the readily available R3 Exhaust system from Proton?![]()

Stock campro cps really need a good 4-2-1 extractor (this also mean removing the catalytic converter) to extract its real power. Yes, just the extractor and maintaining the rest stock exhaust system. Get a better plug cable even the bosch rm90 is enough because the stock cable really suck. Misfire at low rev-high load is common problem in stock campro cps. A good grounding cable also help a lot for this engine. Make sure have 1 cable from coil ground@body directly connecting to battery -ve terminal. A less restrictive air filter like works and knn also a good basic upgrade to do. Try this first and let me know the result. If u using manual, a 200kmh GPS top speed sure achievable (around 220kmh @ speedometer). Even a turbo preve cant catch u from pick up to top speed.
Mod all R3 parts might as well get R3......![]()

R3 one now have to find 2nd hand ones already. But not many letting go also haha!
R3 Model that time was selling close to RM80K while current one with ONLY R3 bodykit is RM61-64K.
Maybe mod cost might be close to the R3 price or they actually earn more by selling the modded parts separately![]()
