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.

Baffle Installation

Zoomie and Chopster Header Baffle Inserts:

Sanderson does NOT provide mounting holes for mounting the muffler baffle inserts due to possible liability issues. Safe installation and proper securing of the insert are the responsibility of the customer or installer.

Baffle Installation Procedure:

  1. First, make sure the inserts are the correct size for the application. Sanderson’s 1.875″ (1-7/8″) inserts are for small block engine applications, and the 2.250″ (2-1/4″) inserts are for big block engine applications.
  2. For NEW installations – Notice that one end of each Sanderson muffler insert is partly closed off with a welded washer.
  3. Use a tape measure to determine the depth of the insert from the end of the tube. Use that measurement to mark the inside of the header tube. The insert depth should be held up slightly from the short-side radius at the lower bend and not bottom out (see image below). Measure the insert depth for every tube.
  4. Insert the muffler into one of the pipes of the header with the partially closed-off end first. DO NOT FORCE. The insert should be snug, but not too tight.
  5. There are various methods to secure the insert. Either drill a hole slightly in front of the insert and install a stove bolt and locknut (or use red Loctite); or drill and tap directly into the baffle ring, using a properly sized bolt with a small amount of red Loctite on the bolt threads
    1. NOTE: Some customers have used sheet metal or self-drilling/tapping screws to hold the mufflers in place, but such screws tend to vibrate loose.
  6. When the mufflers are securely fitted in all eight pipes, the headers are ready to install on the engine.

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 actually 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 your Sanderson Headers with ANY thermal tape voids your header warranty. The best thermal protection for your headers is our Aluminized Ceramic Coating which 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.

Header Warranty

Sanderson Header WarrantyLimited 5-Year General Warranty

Sanderson Street Rod Headers strives to supply our customers with the highest quality parts and services available 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 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.

WRAPPING HEADERS WITH THERMAL TAPE VOIDS THE WARRANTY.

* Extremely compact header designs that 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. 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.
