Notes

This header kit makes noticable increases in power output of your LS based GM truck or SUV! Backed by over 50 years of knowledge and experience, our headers are designed to outflow your stock exhaust manifolds by leaps and bounds. Tri-Y (or 4 into 2 into 1) style headers by design will increase the power of your motor across the widest RPM band possible. That is the beauty of the design, and that is why they are the best street header available. To make these headers last, we built them using industry leading 14-gauge tubing with 3/8" thick flanges. To top all of that off, our headers come beautifully ceramic coated to greatly reduce under-hood temperatures and protect the headers from the environment. All 100% American made, and backed by our lifetime warranty. Install these long tube headers today and feel your vehicle's true power potential!
