JBA install

The install instructions are poor at best. Many more steps required than listed in guide.

Gibson Exhaust Performance Headers Reviews


A must buy for any vehicle!

Reviewed By Robert M (MEMPHIS, TN) Reviewed for a 2012 Chevy Avalanche —6/4/2014 9:07 PM

These headers instantly provided more HP and gas mileage. If you are on the fence about purchasing headers, you shouldn't be, these headers are exactly what I was hoping for. I've purchased a cold air intake, gibson dual exhaust and superchips power programmer over the past years. The headers provided the most noticeable HP and MPG gains. Only issue was the lack of detailed instructions when removing exhaust manifolds. Additional tools required, O2 sensor removal required and not mentioned.

Doug Thorley Headers Reviews


Awesome sound but needed modification

Reviewed By Johnathan M (Jacksonville, FL) Reviewed for a 2008 Chevy Silverado —8/2/2018 8:16 PM

The bad: the crossover pipe didn't line up correctly on my 2008 Silverado 5.3. The exhaust shop had to cut, bend and splice to get it to work. Mine is lifted (suspension and body), so that may be the reason for it. Also, no gaskets included. The good: everything else is good. These are thick and heavy. The description says ceramic coated and the part # is for the chrome version... they are chrome (nice!). Sound is amazing with Magnaflow Performance series 24" (catless)! Very happy customer!
