Description

The Wehrli Custom Fabrication Billet Exhaust Manifold Kit replaces restrictive factory cast parts with high-strength, TIG-welded, CNC machined billet steel components. It is designed to enhance exhaust flow, improve turbo spool up, lower EGTs, and increase power and economy. The kit includes new gaskets, ARP 12PT fasteners, and assembly lube, and is finished in Black Ceramic Coat. No tuning is required for installation.
