MS4 Trans Am Cutout w/Borla Adjustable catback 2002 Trans Am 799 heads 2
This is a video with a warm start up of a 2002 Trans Am with MS4 cam and 799 heads. Car has off road y pipe and mac mid headers. The cutout goes in between passenger tip and muffler. When open, Exhaust freely bypasses the muffle on the passenger tip and some of it still passes through the muffler to the driver side tip. When closed, all Exhaust gas and noise is sent through the muffler and out the driver side tip. The car is a million times quieter inside and out with the cutout closed. Sounds like a bolt on car with stock cats and a loud cat back. Filmed during day, obviously...
