It's time to let your Prowler sound like its supposed to with HighFlo Performance / Sweet Thunder Exhaust! We have a direct bolt-on replacement to allow your prowler to breath better, perform better, and the most important part sound like a HOTROD like it is! We use our aluminized 18" - 2.25" chambered mufflers with our custom x-pipe to give your car that great muscle car tone. We supply you with new accuseal band clamps as well. We offer this in a 24"" version as well, the 18's are louder than the 24's. Also a stainless version is available too.
