Flowmaster Super 10 Series Mufflers Reviews

Very Deep sounding Muffler

Reviewed By joseph l (SAN DIEGO, CA) Reviewed for a 2005 Pontiac GTO —11/13/2014 9:17 PM

Ok Honestly, I like my exhaust pretty loud. Before this muffler I had muffler deletes on my 2005 GTO! It sounded good but at idle it had kind of a splat like sound and not a good tone. WOT sounds awesome! BUt lets get to this Super 10 Muffler by FLowmaster. It's not as loud on a Stock system but, it is loud! The difference I like about this muffler is my torque was a lot more stout with this muffler and the tone is so deep and sounds, seriously awesome on my 2005 GTO. Best muffler I've bought!

Awesome sound!!!

Reviewed By Justin F (Centreville, VA) Reviewed for a 2006 Pontiac GTO —2/10/2009 3:32 PM

I love the sound of the Flowmaster Super 40 Series mufflers. The classic muscle car sound they provide is second-to-none.

great product

Reviewed By Ely W (GREELEY, CO) Reviewed for a 2012 Chevy Silverado —11/24/2015 8:57 PM

Very happy with this muffler. It sounds great and was easy to install. It has a slight amount of drone that cost a star, but all in all as a replacement for a stock muff it is great. Would go this way again if I did this mod over.
