Exhaust Header, 6-3-1, Uncoated

Description 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.  This one is uncoated for customers who wish to arrange their own coating. Manifold gaskets and outlet companion flanges or exhaust system adapters are sold separately. Installation Note: 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.
