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.

Gibson Shorty Headers and Cat-Back Exhaust System

Reviewed By Stephen B (Fort Pierce, FL) Reviewed for a 2004 GMC Sierra —2/11/2014 5:53 AM

Previously installed a Gibson cat-back exhaust system , there was a noticeable sound and performance gain.Just installed a set of Gibson shorty headers , power is more linear but does not seem to have increased performance much. But both are a high quality product , fitment was great and installation was reasonably straight forward.
