GMC Sierra Headers

GMC Sierra Performance Headers

An exhaust manifold essentially serves as a routing system for emissions gases leaving the engine bay. The GMC Sierra manifold directs the exhaust away from the vehicle’s working components and out the rear of the c ar, through the GMC Sierra exhaust pipe. Though sufficient, this is certainly not optimal. GMC SierraBack pressure caused by conventional exhaust manifolds means the manifold itself requires energy to function effectively. With a GMC Sierra exhaust header, much of this problem can be sidestepped.

GMC Sierra exhaust headers amount to what are smaller versions of exhaust pipes working in coordination with one another. Each Sierra exhaust header directs gases away from its corresponding cylinder and enables exhaust regulation that doesn’t result in the same back force that expends so much energy with traditional manifold setups. For those drivers who want a more efficient vehicle with less troublesome exhaust, a GMC Sierra aftermarket exhaust header will serve them well.

I ordered my spacer over the phone and asked for expedited shipping. Wes recommended to me that USPS priority large box will work just fine for this package and told me no need to pay extra. I got my package 3 days after i ordered it. I am pleased with the service and honesty from your company. Tha

Best upgrade for my Sierra. I am very pleased with the quality and sound. I have received my part just in 4-5 days after I placed the order. Thanks Wes!

I would have rated these a 5 if it were not for the fact that they needed some additional sealant around the lens. Luckily I had some left over rubber sealant lying around - I'd read about and experienced this before with my other aftermarket lights. Overall I am very satisfied with the product and the customer service. I was notified of a short backorder (about a week) shortly after placing my order, which happens from time to time. Wes kept me updated and called me as soon as the item left. Great guys to deal with!

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.
