Hi , Me and my wife just bought a 2001 cobra with a bassani stainless exhaust. Every time we get to a certain rpm in every gear there is a rattling sound. I took it to an exhaust place and asked them what it could be and he said bassani is nutorious for having baffles come loose with too many bumps. I really have no clue if thats what it is. Guna replace the factory h pipe with no cat x pipe and install two new cherry bomb pro mufflers. If thats not it then i will move on to other possiblities. The old owner said it also could be something with the clutch. Now it is a possibility but i dont see how. Clutch plate or flywheel??? i have no clue
