    I have a 1938 Chevrolet pickup with a 350 Chevy motor set on a S-10 frame. I can't use lake pipes because of the clearance with the tires setting back because it's on an S-10. Any idea if these would work on my truck and clear the tires?

    I have a 1932 ford with a downs body and a LS1 engine,will this twisted header work and they say the O2 bung needs to b in the collector is that possible with this header or would you recommend another outside the frame header that the O2 sensor was in the collector or does it have to b in the collector and maybe in the rear pipe closest to the block????

    The Twister will work, and the oxygen sensor bung can be installed wherever you need it.

    I saw your beautiful Twister Headers on a roadster this weekend. I want a set for my '32 Ford Roadster with a 350 Chevy engine. My only concern is that they were very loud. I don't know if he had the baffles installed or not. How loud are these headers and are mufflers avaiable instead of baffles?

    The Twister and other outside chassis headers are quite loud. It is possible to increase the amount of packing that surrounds the insert, but it is important not to get too crazy here where it causes excess restriction that raises the EGTs beyond the capability of the header or header coating, possibly damaging either.

    Will the Twister header work with the Factory Five 33 hot rod frame?

    Sep 24, 2015, 09:01

    Hello Mike: We have not yet built a set of Twister headers for the Factory Five '33 vehicle applications. The Factory Five '33 chassis has tubing that runs from the firewall down to the front of the frame, plus two support tubes below that--all right where the header tubes need to be. Although the Twister is built-to-order based upon the available space and specific dimensions of the application, we would need to see pictures of your vehicle with the engine in the chassis, including pictures showing dimensions. Please create a support ticket on our Helpdesk and include pictures of the vehicle.
    Here is a link:


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. See the detail image above left that describes engine sides.

  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.
