Review on 🚗 PaceSetter 70-1346 Shorty Header Review: Enhance Performance for 2007-2009 4.8L, 5.3L Chevy Silverado/GMC Sierra by Brian Trujillo

These manifolds mount directly to the heads with ease. I would recommend buying better quality gaskets for it (all gaskets). The reason I'm only giving two stars is because the headers don't match the Factor's tailpipes. Their deviation is only a fraction of an inch, and the degree of flare is also wrong. Because of this I had leaks and burst 2 sets of gaskets. Finally I cut the factory pipe and moved it around a bit until everything was lined up and fitted properly. My final complaint is that fasteners are cheap, poor quality, and rust quickly. When I got the manifolds + new gasket + fasteners + my exhaustion repair I had spent more than the cost of known manifolds that do not have the above problems.
