These shortie headers are a fantastic way to work some extra horsepower out of your LS powered project. A simple bolt-on installation will have you back out on the road in no time and getting where you're going a little faster. To make these headers last, we built them using industry leading 14-gauge steel tubing with 3/8" thick flanges. Topping 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.
