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.

Bought and installed these original 40 series mufflers on my 2001 monte carlo. It makes a great roaring sound that's controlled as per the throttle response. I can take off with easy acceleration and it makes a noticeable sound (roar) I slam the pedal to the metal and it gets much louder which is exactly the type of sound how and when I wanted. No interior drone. So this was done on my stock everything v6 3.8L engine. Now i can imagine the sound from these mufflers onna v8
