GMC Topkick Exhaust Systems

When you have purchased a GMC Topkick cold air intake for your vehicle, you might want to consider putting on a full GMC Topkick cat back exhaust as well. GMC Topkick Cold air intake system directs more cool air into the combustion chamber, in result, the fuel burns better with colder condensed oxygen. With all these exhaust gases exiting the motor, The exhaust flow is highly restricted by the GMC Topkick catalytic converter and factory GMC Topkick cat back exhaust that created much back-pressure. Installing GMC Topkick performance exhaust system will help to reduce back-pressure dramatically from bigger piping diameter & straighter pipe design. You can find the best GMC Topkick exhaust from our online catalog. Discounted GMC Topkick exhaust systems are now offered with free shipping and way below MSRP.

There was a slight scratch in the clear coat that I had to buff out. All in all a nice piece. I dont think anyone else makes a carbon N54 engine cover. Item reached me in 2 days though, that was impressive.

If you have a newer vehicle, especially European, you have to spend a little extra money on one of these CANBUS kits. Ive been through several other types of HID kits and my lights would flicker, or one side wouldnt turn on, and I would get the warning light on my dash. As soon as I installed this kit, my problems were gone. I'm very happy with this kit - MUCH brighter than any of the other kits Id previously purchased.
