Mufflers sound awesome!!! Not too difficult to install. I have the 40 series on my truck, love sound of both.

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.
