Big Block Tri-Y Under Chassis Headers

Our under-chassis, Tri-Y headers give you high-flow header performance and a custom fit that means you don't have to sacrifice your power steering. Retain exhaust studs in the heads and no more breaking into a water jacket! Plus, unlike most headers, it doesn't capture the starter, and, because it's designed specifically for your application, it installs quickly and painlessly, even with the engine in place. Applicable to '67 and up A-Body B/RB (400-500 hp), '63 & up B-Body and E-Body, with manual or power steering and automatic transmission. Available in raw steel or matte silver ceramic coating. Made in the USA!
