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.

Why Use PowerCaps?

For those looking at the Sanderson Lakes-style Limefire and Jayster outside chassis headers for their street rod, here is a tech tip that might prevent grief, frustration, and damage!

You may already know that the Sanderson lakes-style headers are available with or without connections for an under-chassis exhaust system. Sanderson has offered the ability to have a throaty open exhaust or a quiet and capped lakes-style header using an under-chassis system since the original design.

We have found that there is not much of an issue with stock or mild street rod engines if the installer follows standard installation instructions. However, on applications making decent horsepower, it is possible to damage the header or header coating near the end of the collector where the under-chassis adapter connection is located. The cause of this problem is the turbulence created by the limited distance of dead space just after the under-chassis connection and the end cap on the header (when the header is capped and exhaust gasses are routed through an under-chassis exhaust system). The turbulence in this area causes the EGTs (Exhaust Gas Temperatures) to rise dramatically. In some applications, this could cause the EGTs to exceed the thermal capacity of the header coating—causing finish damage and discoloration. This problem occurs on high-power engines and engines regularly operating at higher RPMs, including applications that regularly experience extended highway driving or on lower-geared vehicles.

The solution is relatively simple but adds cost to the header purchase. We designed a component called the “PowerCap” to solve this issue. The PowerCap slides into the collector tube and smoothly redirects exhaust gas flow from the collector tube into the under-chassis exhaust tubing. The PowerCap bolts securely into your header at the end cap flange, removing the collector horn’s turbulence area. Improved power and torque are additional benefits by improving airflow into the under-chassis exhaust. Although the PowerCaps are recommended for higher horsepower applications, they also benefit all applications using the under-chassis exhaust connection.

PowerCaps capture hidden horsepower on applications using under-chassis exhaust connections. Under-chassis adapters allow you to run a quieter under-chassis exhaust system, and adding the PowerCaps increases power and extends the life of your headers.
