Purchased flowmaster 60 series to put on a 2008 Chevy HHR. It really sounds good but haven't had it on long enough to see how it affects overall performance.

Installer on a 5.3 SSR. Has the sound I wanted. Not too loud, I assume because of the Catalytic Converters. Added pipe to the front so it is installed closer to tailpipes under the bed, so no noticeable Drone inside cab.
