Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
HAHA 2 days driving the car and the coppers got me. now i cant drive it at all.
Do you have a pipe that runs right through? or is it just cut after the cat??? if so... please dont drive! bad!
The power loss is due to N/A cars requireing back pressure, yours has zero... haha.... it wont hurt the engine but i dont reccomend keeping it that way for long!
