???u mean engine sound very loud, i think is because you were doing a burnout in the rain, front tyre no grip i believe.

Ya, the front tyre no grip. It happen to my car too during heavy rain.

for that budget, besides looks and a little improvement and additional  a lot of butthurt, just stay stock....or change the whole system

omg today when i drove back to home in rain, suddenly my car shaking and have strong "roar" sound when i press oil pedal.

Very scary~ the feeling is like something stuck there, very tough.
So i stop my car beside and wait for awhile, because raining.

Then try to start my car again, the problem gone.

Anyone facing this problem? or in raining time?
