I'm kinda old school so I went with the 50 series. Sounds mean on take off but purrrs like a panther on the highway.

I purchased the Flowmaster American Thunder exhaust from Auto Anything with a 20% discount and rebate. I also purchased the BBK o/r x pipe. Had it installed in couple of hours and sounds great. Now my 04 Mustang GT sounds like it should.
