This 2.5″ diameter performance X-Pipe with Mid-Pipes creates power while adding a great sound to the C5 / C5 Z06 Corvette systems. In testing, customers and racers alike noticed the power increase you’ve come to expect from BORLA(r), and all commented on the great exhaust tone being emitted. This Merge X-Pipe is a perfect compliment to the famous BORLA(r) Cat-Back(tm) systems and is even lighter than the stock system, mainly due to the premium, high-quality T-304 austenitic lightweight stainless steel used in every BORLA(r) exhaust component. Additional attributes include an extremely simple, bolt-in replacement for the factory mid-pipe that further enhances that famous BORLA(r) growl of power. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. While many exhaust companies talk about racing, BORLA(r) mufflers, systems, and other exhaust components are tested every single weekend on race tracks around the world. The BORLA(r) success is unmatched, and that effort transfers to the BORLA(r) street systems. BORLA(r) backs this part with an unequaled Million-Mile warranty.
