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

top speed is honestly useless! its how you get to that top speed that counts!

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.

bro wanna play this engine..just keep it basic..invest more on long term stuff for the car...such as suspension, brakes etc...things can be sued when you do an major engine upgrade or engine swap... for the engine..you got ur exh setup covered alr ...what ever changes you make from here wont make much difference.

since you like more top.. you can opt for a adjustable cam gears, and set your cam for power up top.get an emanage or any piggy back and get the car tuned... can suggest to do more...but in the end you if gonna change engine , bettere not spend too much on stuff you cant reuse... like semi racing cluth, port and polish and skim the head... etc2... thats why focus on the car handling and/or braking.. things that can maintain when upgrade engine. piggy back can reuse... but must retune next time if you change engine or upgrade bot.

exactly bro...for suspension about to complete as for now has coilovers, strut bars and soon arb...then brake and performance on list

for adj cam pulleys right....make both intake and exhaust increase the overlap and thus slightly move the power band higher range......make intake advance and exhaust retard also increase overlap and more for high range...but what is the diff between this two setup ? sorry still noob

I've seen a brand new supercharger made for the campro for sale for RM6k. If you have the budget this is a good mod to have power across the whole rev range

The RM6k one in FB has been there for quite a while already. I would say it is a good upgrade too :biggrin:
