Gibson Stainless Headers

Excellent quality, 14 gauge pipes. Easy install, both sides slid right into place, bolted right up, no coaxing, no tweaking. Sound awesome, 200 miles on them so haven't checked mpg yet.

Great sales experience on a quality product

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.

I have a 2010 GMC Sierra 2500HD with a 6.0 and I have already installed Gibson's catback dual rear exit exhaust and Bully dogs power programmer that improved power and torque, then I added the headers and a Bully dog intake the greatly improved throttle response. Overall very much worth the time, effort, and cost

I haven't put them on yet but they look sweet and I hope I gain As much power and increase my gas mileage by as much they say they can. But they look really good and looks like a good product.

Excellent
