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.

Banks Monster Exhaust System Reviews


EASY AS PIE AND AWESOME UPGRADE!

Reviewed By Cary B (MCKINLEYVILLE, CA) Reviewed for a 2003 GMC Sierra —6/25/2013 5:22 AM

I ordered the Banks Monster Exhaust System for my recently acquired 2003 GMC Duramax Diesel. It was super easy to install, fitment was perfect and it really makes my truck sound like it is ready for it's next upgrade (a PPE Tuner)!
