Can anyone think of an obvious reason why my exhaust would become "quieter" after having a new clutch and flywheel installed. A few days ago I had an RXT installed, and when starting the car there's a slight "wisp" sounds and the car just sounds quieter at idle. I have a cat-less exhaust setup and it's typically pretty loud. My kids can usually here me pulling up to the house, so they noticed it as well. They did have to disconnect the battery so maybe something changed after that. My CD player is also not showing the "cd error" during startup as well. Just checking to see if it's anything obvious.
