Sanderson's Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, Sanderson applies a multi-layer inside and outside aluminized ceramic coating in-house and then polishes the coating to a high luster. This aerospace and military-grade technology adds excellent protection to your headers, while offering the benefit of thermal control in your engine bay. It also improves cylinder scavenging of exhaust gases, and increases the longevity of your header investment.

When sitting in driver's seat and engine in front of you, the LEFT header would be the Driver's Side on LH drive vehicles; coincidently, means the RIGHT header is on the passenger side.

Sanderson PowerCap (cut-away, shown inside header)For those of you looking at the Sanderson Lakes-style Limefire and Jayster outside chassis headers for your street rod,here is a tech tip that might save you grief, frustration, and possible damage to your headers!

You may already know that the Sanderson lakes-style headers are available with or without connections for an under chassis exhaust system. The ability to have a throaty open exhaust, or a quiet and capped header using an under chassis system, has been something we have offered for as long as we have built these headers.

We have found that if you have a STOCK or MILD engine in your street rod there is not much of an issue by following the normal installation instructions. However, if you happen to have an engine making decent horsepower you might damage the header or header coating near the end of the collector where the under chassis adapter 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 being routed through an under chassis exhaust system). The turbulence in this area causes the EGT's (Exhaust Gas Temperatures) to rise dramatically, and in certain applications this could cause the temperatures to exceed the thermal capacity of the header coating---causing finish damage and discoloration. The problem only seems to occur on high power engines, and engines which are regularly turning considerable RPM's---for example, considerable highway speed driving.

The solution is relatively simple, but adds costs to your headers. Sanderson designed a component and named it the "PowerCap" to solve this issue. The PowerCap slides into the collector tube and provides a smooth redirection of exhaust gas flow from the collector tube into the under chassis exhaust tubing. The PowerCap bolts securely into your header using the end cap flange, thereby removing the turbulence area in the collector horn. Another benefit of using the PowerCaps is improved horsepower by improving air flow into the under chassis exhaust. Although the PowerCaps are recommened 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 quiter under-chassis exhaust system, and adding the PowerCaps increases power and extends the life of your headers.

Exhaust Exit Options:

Default Limefire configuration consists of under chassis connection and a basic metal block plate.

The Sanderson Limefire is offered without the under chassis connection and the option of a slip-in baffle insert. Tip options include a finned aluminum block plate or turnout tip. The turnout tip can be used with the standard block plate (using under chassis exhaust piping), or without, as the exhaust exit point.

NOTE: We recommend the use of PowerCaps on all Limefire headers connected to under chassis exhaust, but especially on those applications making decent horsepower.



  1. The Patented Leak-Free Design that Sanderson Headers offer you is the only leak-free flange design on the market ... Do Not Attempt To Use Flange Gaskets! The raised flange on the Sanderson Headers will buckle the gasket during tightening and actually cause a leak!
  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 your Sanderson Headers with ANY thermal tape voids your header warranty. The best thermal protection for your headers is our Aluminized Ceramic Coating that is available for every Sanderson Header.

Limited 5 Year General Warranty

Sanderson Street Rod Headers strives to supply our customers with the highest quality parts and service available in the street rod industry. In keeping with this, we warrant and will repair or replace, at our option after inspection in our facility, any of our products which are found by us 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, and 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 for which they 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.



* Extremely compact header designs which locate the collector in close proximity 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. All other Warranty conditions apply.
