hi guys! I m helping one of my fren. I would like to know after the cat, there is a mid pipe silencer. I would like to know by removing mid pipe silencer, would there be any gain in car performance??
I only know the exhaust noise will be loud but dunno gt any gain or not.
assuming the cat hv changed to high flow cat and muffler have changed too. the exhaust pipe have change to 2 inches.
pls advice mi, thnks!

always remember - u gain something.. u lose something..

i beg to differ. there will be quite a substantial horsepower gain if you change your entire exhaust system. pickup might actually suffer because your ECU is not tuned to maximised performance to the change in your exhaust system. so best is to do an ECU tuning after you have change your exhaust system.
upsizing your mid pipe diameter and removing the silencer means you have more capacity for better air flow.

Exhaust system is the most obvious in hp gain... Problem is, there's no LTA compliant one for Rio... high risk... Recently newspaper showed the things they catch.. one of the most common ones are exhaust, headlights like HID, tinting... Thanks to the newspaper, I finally know where "Orchard Gudang" is...
