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.

just right

Reviewed By Tim R (RADNOR, OH) Reviewed for a 2015 GMC Sierra —6/30/2015 5:52 AM

the 50 muffler is the right one for me and my sierra. it is just loud enough to let you know there is power under the hood, but it will not vibrate inside. unless you punch it, you would not notice it much. you can tell in normal driving it has more torque and horsepower.
