The Certified Automotive Experts CAE-045-C Turbo Headers are designed for custom Big Block Chevy (BBC) turbocharger builds using 396, 402, 427, 454, 496, 502, or 572 cubic-inch engines. Featuring 2.25-inch primary tubes, 3.5-inch V-band collectors, and forward-facing outlets, these headers are intended for custom turbo fabrication, engine swaps, and high-performance applications.
Constructed with mandrel-bent tubing, TIG-welded joints, and CNC-machined 5/16-inch-thick flanges, these headers feature a silver semi-gloss ceramic coating. The kit includes left and right headers, V-band collector flanges, V-band clamps, exhaust gaskets, and installation hardware.
Important: These headers are designed for custom fabrication, not guaranteed vehicle-specific fitment. Verify engine bay dimensions, chassis clearance, steering components, suspension, and turbocharger placement before installation.
