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


Purdy Headers!

Reviewed By Bob B (Tacoma, WA) Reviewed for a 2000 Toyota Tundra —1/3/2018 6:11 PM

I ordered these and they arrived well packaged and quickly. I had a shop put these on for me along with some Magna-flow catalytic converters and a Flowmaster cat-back system, so I cant really comment on how hard they are to put in. I do want to say that they did not come with new exhaust gaskets for either end of the headers. I noticed a definite increase in horsepower and engine response, but I replaced the whole exhaust from the block back. Overall I give em 4 stars (a bit expensive)
