Header Warranty

Limited 5-Year General Warranty

Sanderson Street Rod Headers strives to supply our customers with the highest quality parts and services in the street rod industry. In keeping with this, we warrant and will repair or replace, at our option, after an inspection in our facility, any of our products that we found to have failed due to defects in either material or workmanship.  This warranty is activated by the return of the Warranty Card enclosed with every pair of headers. It is effective for FIVE YEARS * from the date of purchase, as indicated on the original invoice.

This Warranty does not cover products that fail due to improper motor tuning, alteration, disassembly, or damage caused by racing, misuse, neglect, abuse, improper installation, and/or accident or when used on applications that were not designed or approved. We are specifically not responsible for the costs of removal, installation, transportation, destruction of other components, inconvenience, loss of time, or other personal damages or for any other associated costs, including the application of aftermarket coatings applied by others. Sanderson Street Rod Headers shall not be liable for any and all consequential damages occasioned by the breach of any written or implied warranty pertaining to this sale in excess of the purchase price of the product(s) as found on the original invoice.

WRAPPING HEADERS WITH THERMAL TAPE VOIDS THE WARRANTY.

* Extremely compact header designs that locate the collector close to the exhaust ports are very sensitive to engine tuning. Improper air/fuel mix or timing of ignition and/or valvetrain can cause early failure due to excessive heat. For this reason,  part numbers CC2 and CC3 are offered with a two-year warranty period only. This includes header sets that utilize one of these headers as part of the set (part numbers CC4 and CC14, for example). The compact header side will hold a 2-year warranty. All other Warranty conditions apply.

Installation Notes

1. The Patented Leak-Free Design on Sanderson Headers provides the only leak-free flange design on the market … Do Not Attempt To Use Flange Gaskets! The raised flange on tube-style Sanderson Headers will buckle the gasket during tightening and cause a leak!  It is only OK to use a header gasket on the cast-series header sets (QP1000 and QP2000) Click here for the header installation procedure.
2. Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser’s responsibility to verify local regulations for compliance.
3. Wrapping Sanderson Headers with ANY thermal tape voids the header warranty. Our Aluminized Ceramic Coating is the best thermal protection for your headers and is available for every Sanderson Header. For additional information on why using header wraps is a problem, please read this tech article by Century Performance Center which addresses thermal coatings and header wraps.

Hemi Engine History

It is crucial for us to know which Hemi engine is in your vehicle because there is more than one. (Sam of Century Performance Center, Inc provides this article.)

First, Some History:

Although Chrysler trademarked the term “Hemi” somewhere in the 1950s, it wasn’t until the second generation Hemi, the 426 that showed up in 1964, that Chrysler started using the Hemi term to officially define the name. The name originates from the hemispherical cylinder head and, more specifically, the combustion chamber design. The 426 Hemi, often referred to as the “elephant,” became well-known quickly for its use in NASCAR and a few special production vehicle applications. The trademarked name was not officially recognized from a commerce standpoint until February of 1966, 2 years after virtually everyone knew something about it.

However, while most people immediately recognize the term “426 Hemi”, it was not the first Hemi engine. The Chrysler FirePower (not yet coined as a Hemi) 331 V8 was the first to find itself between the fenders of a few 1951 model year vehicles. And there were others … which gets us here.

Each Hemi engine group uses a different exhaust port and bolt spacing. Therefore, Sanderson Headers for the Hemi engines vary slightly to include specific port and bolt layout flanges and varying primary tube bend radiuses to accommodate different exhaust port exit angles. Here are the four Hemi engine groups for which Sanderson builds headers. You will see in the list below that the Dodge and Desoto Hemi engines include a dimension. This is the easiest way to determine the difference between those two engine groups. Please refer to the graphics below the list to explain this dimension.

NOTE: Sanderson does not offer header sets for late model 5.7L, 6.1L, 6.2L, and 6.4L engines.

• Chrysler 426 Hemi
• Chrysler/Imperial FirePower  331-392 (331, 354, 392)
• Dodge 241-325  (14-3/8″)  (241, 270, 315, 325)
• DeSoto 276-345 (14-3/4″) (276, 291, 330, 345)

This first graphic shows the 14-3/8″ spacing for Dodge Hemi engines.

This second graphic shows the 14-3/4″ dimension of the DeSoto Hemi engines.
