Flowmaster Super 10 Series Mufflers Reviews

Perfect muffler for my truck

Reviewed By brian e (Columbus, OH) Reviewed for a 2002 GMC Sierra —4/12/2015 5:09 AM

I had a 40 series flowmaster single in/out with stock tailpipe on my GMC 5.3, it sounded good at idle but disappeared at WOT when I really wanted to hear it, so I bought the super 10 to replace it, I dumped it right by the rear axle, this thing sounds amazing, exactly what I was looking for, I find myself flooring the gas peddle just to hear that amazing exhaust rumble. I couldn't be happier and if you are scared it will be too loud, don't be, it isn't super loud, but it is deep/aggressive.

Reviewed By nicholas b (ARGYLE, NY) Reviewed for a 2002 GMC Sierra —8/3/2013 5:35 PM

This muffler was easy to install and looks great. Exactly what I was looking for of nice tone and loud but not so loud it will attract attention from police.

Flowmaster super 44

Reviewed By Peter C (New Vernon, NJ) Reviewed for a 2002 GMC Sierra —10/31/2008 1:49 PM

Sounds GREAT on my sierra 4.3 V6 Strong rumble at low rpm and powerful deep sound from about 1800 rpm and up. Interior resonance is not bad at all, considering how loud it is outside.
