Awesome buy

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.
