CORSA's Ultimate C5 Crossover Pipe

The Corsa crossover pipe design provides improved, balanced side-to-side exhaust flow for increased power and reduces the exhaust "idle burble" and popping on deceleration in most fifth-generation Corvettes. CORSA's XO-Pipe Crossover Pipe™ improves exhaust flow, at the same time smoothing out the LS1 engine pulses for better throttle response and a cleaner sound. The perfect complement to CORSA's Pace Car Edition muffler system!

1997 Corvette Exhaust Design Change Set the Stage
Automakers and performance enthusiasts have been installing balance tubes in dual exhaust systems for years. Tests have shown that balancing the backpressure between the independent exhaust branches increases power and reduces resonance. When Chevrolet introduced the C5 Corvette it installed a simple "H"-pipe balance tube. It was roughly two inches in diameter and provided adequate flow between the 2 1/2-inch catalytic converter pipes.

For reasons unknown, a running change was made to the "H"-pipe sometime in model year '97. The change resulted in using a smaller connecting passage of approximately 5/8-inches, thus rendering the "H"-pipe ineffective. From that change forward, C5s have had the smaller balance connection that contributes to a popping exhaust sound on deceleration and a gurgling, or "motorboat" sound at idle.

 



CORSA's X-Style Crossover Pipe Improves Exhaust Flow CORSA Performance, makers of the World's best-selling C5 Corvette exhaust system featuring its patented *Power-Pulse RSC™ technology, has focused its attention on developing the ultimate C5 Crossover Pipe. This design, based on sound engineering principles, provides improved, balanced side-to-side exhaust flow for increased power and eliminates the exhaust "idle burble" and popping on deceleration in most fifth-generation Corvettes. CORSA's XO-Pipe Crossover Pipe improves exhaust flow, at the same time smoothing out the LS1 engine pulses for better throttle response and a cleaner sound.

CORSA's full-length, 2 1/2-inch XO-Pipe Crossover Pipes are made of 16 gauge 304L stainless steel with mandrel bends and are designed to bolt on after the catalytic converter and mount to the muffler over-the-axle pipe flange. Each CORSA Crossover Pipe comes complete with installation instructions and all necessary hardware and gaskets. No welding required, just basic hand tools. (a chain-style pipe cutter is recommended for ease of installation). Made in the USA, CORSA's Crossover Pipes are "guaranteed for as long as you own your C5."
