I have American Racing catted long tube headers, and a Corsa Extreme with a double helix x-pipe and it's the loudest car street I've ever heard short of open headers on some old big blocks. Adding the Long tubes caused a significant increase in volume.
I have the extreme setup, (Double Helix x-pipe, Extreme Mufflers and quad tips). I am looking to trade for a quieter setup. Where in PA are you? I'm in central NY between Buffalo and Syracuse.
I Agree, if I were drag racing the car I would probably have no issue with the converter as-is but it just slips too much. Just about the only thing that I need to change.
