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.

All I can say is wow... the sound from this muffler is incredible, when you have a V8. Great flow and really made my truck sound mean. Definitely has a good amount of drone around 1200 rpms but throughout the rest of the rpm range it sounds good... If you want to get noticed and be heard from blocks away, this is the muffler for you.
