Hey guys I know there are couple of forums on this but I just wanna make things clear....

For now my car is std engine wise and mainly upgrading on handling but wanna get into performance next. So what would be the ideal exhaust setup for campro ? I just want power more to mid and high only and don't really care on low. Is 421 header with 2" pipe all the way back and straight flow muffler setup will be ok for Campro Manual ?

Std engine huh, i suppose 421 should be ideal for your demand. 4-1 shines for utter high rev prepped engine(aftermarket internal ofc) but you'll sacrifice both low and mid range. What displacement is your engine? You would want to consider a higher flow cat-con as well.

1600cc campro persona.....currently std engine with aftermarket open pod only but planning to do more mods in future. Aim is mainly for pickup... Top around 180-200kmh enough.....current setup 421 with spiral bullet and straight flow muffler with std piping but wasn't really satisfy.... Hehehehe

You said you don't care about low rpm but then wants pick up, that's a bit contradictory. For good pick up would need good low-mid range response.

Seriously - modifying this car to get mid-high torque will be a challenge. An exhaust isn't going to help since this car was designed for the highend rev range. You're better off changing your expectations. Or just drive hard and fast in the top rev range all the time.

Eibach sucks

Eibach pro kit for putra.
Front - 2 fingers.
Rear - 5 fingers.

Just after a week, the front started to give "ekkkk ekkkkkk" sound on the driver side whenever i pass through road bumps or uneven road. And what's more? The ABS light also blinks occasionally (wheel touching the ABS wire until it hurts). I went to tyre shop and asked them to put rubber. But the annoying sound is still there. Dunno whether the Monroe absorber already kong or not. But there's no sign of any...
