Increased performance through efficient flow…Greater durability through high quality, T-304 austenitic stainless steel, material and a unique, stiffened, flex joint.

Each header is built from premium T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.

Best of all, it's made in the USA and backed by the BORLA® Million-Mile Warranty. Just what you‘d expect from the world‘s most experienced (and most winning) exhaust brand.
