Small Block Hi-Flow Tri-Y Under Chassis Headers

Designed to work with '67 & up A-bodies, '62 & up B-bodies, and '70-74 E-bodies for engine styles 273, 318, 340 & 360.

Our Small Block Headers are built only ten sets at a time, and each set is individually tested for fitment, quality and accuracy.

Our new under-chassis, Tri-Y header system gives you high-flow header performance with a custom fit that means you don't have to sacrifice your power steering. Retain exhaust studs in the heads — no more breaking into water jackets! Plus, unlike most headers, it doesn't capture the starter, has excellent spark plug clearance, and is easily installed from the top down. Works with manual or power steering.

CHROMEX (CERAMIC) PLATING is our best performance coating. Its thermal barrier characteristics provide a dramatic reduction in radiated heat. This means reduced under-hood temperatures, accelerated exhaust gas velocity and a longer life expectancy for the entire exhaust system, not to mention chemical and corrosion resistance.

SATIN BLACK (CERAMIC) PLATING* is our stealthy, semi-flat black alternative to the Chromex performance
coating. It shares the same
thermal barrier, heat
reduction, accelerated
exhaust, and corrosion
resistance characteristics
as the Chromex ceramic

*Special order, call for availability.

CHROME NICKEL PLATING is a good coating at a reasonable price. It resists corrosion and protects against rust. It has a bright shine, but it does change color with heat.

BARE METAL (uncoated) headers are our least expensive exhaust solution, but they will rust unless painted or plated.

Our ceramic plating is done at Performance Coatings in Auburn, WA. Please visit their website for more information about ceramic plating.
