Gibson Exhaust Performance Headers Reviews


Great sales experience on a quality product

Reviewed By Daniel F (North Las Vegas, NV) Reviewed for a 2010 GMC Sierra —8/14/2017 1:33 PM

Quick delivery of well packaged product. Instructions about preparing to install the headers were great. Complete project took about 6 hours and I was not hurried. These shorty Headers gave my 2010 6L GMC 2500 exactly what I was looking for... about 10% better fuel economy and 5% more mid-range power while towing my RV.

Awsome exhaust system

Reviewed By Robert C (Chino Valley, AZ) Reviewed for a 2014 GMC Sierra —8/12/2017 6:26 PM

I saw improved performance immediately, in addition, I got a cool throaty sound as well. If you're looking for either of these two features, I would strongly recommend this exhaust.

Looks good sounds good

Reviewed By Gary S (Altura, MN) Reviewed for a 2017 GMC Sierra —8/11/2017 6:07 PM

A great product well made just need to be patient matching tailpipe positions and angles. Recommend you tack weld all joints then fully tighten clamps.
