We are a manufacturer of innovative off-road headers and a variety of other products for demolition derby, truck/tractor pulling and mudding, generators, pumps, and other applications. Each set of headers are hand crafted to exit through the hood and customized to fit a large variety of engines. DEC Headers offers high quality craftsmanship, very reasonable prices, and superb customer support. We make headers specifically for you and your engine.

We do not make headers that go under the vehicle, Manderal bent pipes, or stainless steel pipes.  We use a standard exhaust shop bender and can compensate for the offset of the heads upon request.

Our flanges are made for the stock heads.  If you have after-market heads, the flanges MAY NOT fit (we haven't looked at all of the after-market heads available).  Call us, we do have some after market flanges.

Please allow up to 3 working days manufacturing time and up to 5 days shipping time.  Next Day Air and 3 Day Select shipping is UPS delivery time, NOT manufacturing time.  If you're in a hurry, call us.

We accept PayPal, money orders, VISA, Master Card, Discover, and American Express.
