GMC Topkick Performance Headers

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

GMC Topkick exhaust headers amount to what are smaller versions of exhaust pipes working in coordination with one another. Each Topkick 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 Topkick aftermarket exhaust header will serve them well.
