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.

Nice replacement that shaves some serious weight, growls low, isn't too loud. Does drone for me a bit in 4 cylinder mode. If your truck is like mine go find some 3 inch Outside Diameter piping and 3 inch inlet outlet muffler and they'll go together well
