Notes: You just finished swapping that LS Motor into your Chevelle. Why choke it up by running the factory exhaust manifolds that leave much to be desired, and why drag a set of long tube headers on the ground every time the road gets a little bumpy? This killer set of headers is just a little shorter than true long tube headers. We designed these to give you the maximum in performance while keeping them short enough so they don’t smack the ground like long tube headers are known for. Of course, the shorter design makes for a bit easier of an installation than long tubes so you don't need to be lowered to run these. To make these headers last, we made them out of industry-leading 14-gauge tubing with 3/8" thick flanges. Topping all of that off, all of our headers come beautifully ceramic coated to greatly reduce under-hood temperatures and protect them from the environment. All of this is 100% American-made, and backed by our lifetime warranty of course!

WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information go to www.p65warnings.ca.gov

ALUMINUM: Most of the aluminum alloys used today contain some level of lead, usually less than .1%. Lead is known to the state of California to cause cancer and reproductive harm. Most aluminum alloys are physiologically inert in their solid form, and the lead is contained within, however user-generated dust and/or fumes may pose a hazard if inhaled or ingested. Heating beyond a certain temperature may also provide avenues for exposure.

STEEL (steel bolts): Steel is an iron alloy with several metals including Nickel and Chromium. Both Nickel and Chromium are known to the State of California to cause cancer and reproductive harm, respectfully. This warning applies to stainless steel as well.
