Your 6ports will open very easily. You can rev the engine and see them open at only 2000rpms . That's how bad my na engine got to be.

hey dumarjo, we need to setup a meet when all the snow melts down.....i`ll give you some tips and we can check out your cats....your best bet is to get a bonez race pipe and replace all your cats, clogged or not. its not that loud with stock mufflers and the power gain is just great.



are you driving it during the winter?
