Well just got my '04 GTP, and it needs a new Catalytic Converter... Its rattling and smells. The car has also just recently developed a nasty sounding exhaust leak. I am wondering what all out there is offered for high flow cats. I wouldn't mind a lower exhaust note, but i don't want that raspiness that all you people want. I own a BUILT V8 car and don't need to have a mock V8 sounding car. I want it quiet when i'm cruisin.
