The American Thunder Classic Axle Back Kit produces good sound quality. I have these on a convertible. They do drone some and it seems to be worse with an automatic transmission. I am pleased with the kit. I have these on a Mustang Coupe as well and the drone is not as bad and it is a 5-speed. If I had to do it over I would probably buy the cat-back kit. But, I would stick with Flowmaster because it sounds American.
