The Corsa Sport Series Exhaust System improves performance and sound. Factory exhausts are restrictive, hindering exhaust flow and sound with small-diameter piping and oversized mufflers/resonators. The Corsa Sport system provides an unmistakable Corsa growl without being obnoxiously loud or droney, using high-performance mufflers and resonators engineered for maximum exhaust flow. This results in dyno-proven performance gains and up to 14 decibels of added volume. All pipes are mandrel bent for smooth, efficient exhaust flow. Constructed from corrosion-resistant T-304 stainless steel, it prevents rust and scaling, unlike common aluminized steel aftermarket systems. Installation is a straightforward bolt-on process, requiring no welding or modifications on most applications, with clamp-on slip joints and factory-style hangers.
