Flowmaster Exhaust Systems Reviews

Flowmaster: the awesome exhaust experience

Reviewed By william m (new castle, DE) Reviewed for a 2003 GMC Sierra —9/24/2013 8:38 AM

Delivers the sound I wanted; not obnoxious, a sweet rumble at idle and a very mellow reminder at cruising speeds. I would heartily recommend this cat-back system. It bolted up just as described and offers a great looking finish with the chrome tips. Be advised you probably will need to purchase exhaust hangars because the ones you have will be difficult to re-use and/or are aged.

MBRP Exhaust Systems Reviews

Awesome Product

Reviewed By Sam D (AMES, IA) Reviewed for a 2003 GMC Sierra —7/29/2013 7:26 AM

A friend of mine liked my MBRP system on my truck so much that he had me get him a kit for himself that we put on and it looks great and sounds just as good! Gives you a nice deep tone without all the drone in the cab.

let me get some air!

Reviewed By Charles S (New Braunfels, TX) Reviewed for a 2003 GMC Sierra —6/27/2013 3:32 PM

as far as i can tell now my 5.3 engine really likes this exhaust system. my first drive after the install it felt closer to a stock fuel injected 350-that i had in a 1996 silverado.a dramatic increase in low in torque resulting in ouicker start i am real happy as these resuts are also due to an afe cold air intake.go for it-fellow 5.3 owners!
