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 have the full H&R set up on my car and I love the quality of the parts. I have sold my Eibach springs to get the H&R coilover and I know my decision is right! Thanks Ilovebodykits

Great product, very smooth unlike some bodykits, my body guy was amazed on the product said will have it done sooner than thought, I did tho however have to drill 2 holes where the side markers go, but easy enough, everything else matched up and fit perfect to all the body lines very easy do it yourself. Amazing kit very pleased
