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.

2015 Chevy Colorado 3.6

Reviewed By Frank R L (Brick, NJ) Reviewed for a 2015 Chevy Colorado —4/28/2015 8:50 PM

Stock exhaust was so quiet you had to check the tach to see if it was running. I called Magnaflow and asked if the exhaust system my dealer mentioned was quiet, the answer was "YES." It has the largest muffler we have. When it was installed it was NOT quiet. The only option was to add a resonator. The replacement system was a direct fit no alteration install. The resonator was a custom install that had to be welded in!! Fortunately with the resonator it is quiet but noticeable.
