Improve your engine’s performance with Good Parts 6-3-1 tuned exhaust header. The 6-3-1 configuration with equal length primary and equal length secondary tubes has been proven to be the most effective in improving performance over a wide RPM range. Good Parts headers are designed to allow easy access to the fasteners attaching it to the head. Coated with Cerakote “Glacier Black” 1800 degree ceramic coating to reduce surrounding temperatures, protect from corrosion and withstand surface temperatures up to 1800 deg F. This coating is sprayed on the outside surfaces but not sprayed through the full length inside the tubes.
Manifold gaskets and outlet companion flanges or exhaust system adapters are sold separately.
The original TR250 and 1969-71 TR6 intake manifolds have an unused protrusion on the bottom of the casting that must be cut off to clear the header pipes.
Cerakote coatings are air cured to a “partial cure”. Full cure is achieved after it is installed on a broken in, fully tuned engine and run at idle or driven normally for one hour. Care must be taken to avoid damage due to excessive heat during final curing. Do not install the header on an engine that needs to be broken in as damage to the coating will occur.
