Sanderson's patented flange design requires no gaskets

The Sanderson Jayster header is named after Sanderson header designer and custom fabricator Jay Wangerine. The Jayster is a new design of the classic lakes style outside chassis header. The unique four-into-one tubes are an eye-catching addition to any roadster or highboy.

The Jayster is available in three primary tube sizes. Tube selection is based upon engine size, power output, and type of use.

NOTES:

  • Dimensions provided are for standard (typical) applications. For wider frames/bodies, such as 40’s pickups, please CALL US for assistance. Sanderson can adjust the dimensions to fit virtually any chassis/body width (extra charges may apply).
  • If your engine is making pretty good horsepower and using an under chassis exhaust,  please add PowerCaps to your order! Review “Why use PowerCaps?” information tab.

Comes with all hardware necessary for installation.

NOTE: Turnout tip, Finned Block-off Plate, and under chassis adapters sold separately

OPTIONS:

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.

What is a D-Port?

We often see confusion in what is considered a D-Port cylinder head. The problem originates in the technical understanding of what constitutes a true D-PORT versus a D-shape. The D-Port roof extends well above the centerline of the exhaust port, whereas the D-shaped port fits nicely inside what is deemed a standard port dimension.

 

Vortec-Style Heads

NOTE: This issue concerns STRAIGHT PLUG Vortec-style cylinder heads

Vortec style (and this includes non-GM aftermarket) cylinder heads use a different spark plug spacing on the center two spark plugs. Many exhaust headers will require specific dimpling to ensure adequate spark plug clearance when used with the Vortec-style heads.

If unsure, please measure the center-to-center distance between the center pair of spark plugs on your heads. The standard distance is 4.5″ (11.43 cm) versus 4.0″ (10.16 cm) on the Vortec heads. See image below:

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 save some grief, frustration, and possible damage to the 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 lakes-style header using an under chassis system has been something Sanderson has offered since the original design.

We have found that on stock or mild street rod engines there is not much of an issue if following the normal 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 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 operating at higher RPMs—for example, considerable highway driving on lower-geared vehicles.

The solution is relatively simple, but adds cost to the header purchase. Sanderson designed a component called 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 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.

Install Notes

 

  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! Click here for 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 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. Please read our tech article that thermal coatings and header wraps.

WRAPPING HEADERS WITH THERMAL TAPE VOIDS WARRANTY.

* 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.
