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.

Great replacement for stock cats. Noticed significant increase in power and good sound with Flowmaster muffler . No problem with codes from o2 sensors with new parts. A lot less expensive then stock factory parts.

I have the 5.3 Silverado with magnaflow cats and 3 in piping. I have it dumped before the axle. 20 Inches of piping after the muffler with a turndown..sounds amazing especially cold start. Very deep and very mean
