Gibson Exhaust Systems Reviews

Cheap, Quick, Easy and Sounds Great!

Reviewed By Scott S (HILLSBOROUGH, NJ) Reviewed for a 2004 GMC Sierra —7/16/2015 8:13 PM

Couldn't of asked for a better setup. Local shop wanted over $1000 to replace my old busted flowmaster exhaust. Glad I found the Gibson exhaust for a great price.

Flowmaster Exhaust Systems Reviews

Great sound

Reviewed By Shayne R (SWANTON, OH) Reviewed for a 2004 GMC Sierra —1/28/2015 9:11 AM

I love the looks of this on my 04 GMC Sierra. Sounds great as well. Mostly easy to install minus shearing off the studs from the stock mounting point. Although flow masters kit pre planned that as they supplied new bolts for that reason.

aFe Exhaust for Duramax

Reviewed By Gregory B (North East, MD) Reviewed for a 2004 GMC Sierra —6/13/2013 11:37 AM

I purchased the aFe exhaust after reading a test article that documented HP and torque gains. Installed the system on GMC 3500 with Duramax. Very impressed with the quality and completeness of the kit. Installation was easy, even after losing the directions and fit is perfect. In fact, it took twice as long to get original system off. Sound quality is good - aggressive, but not annoying or droning. I could not be more pleased with the system, especially at the AutoAnything sale price.
