These traditionally styled shotgun pipes also produce class-leading power gains. PowerPort crossover makes for a significant power increase from just off idle to redline, which leads to a deep and aggressive exhaust tone. PowerPort increases power and overall performance by providing superior scavenging of exhaust gases over most standard exhaust systems; similar to what you might expect from a 2-into-1 system. Large 2.5", 222°, full-length heat shields fit from the exhaust ports to the billet tips for a seamless look and no bluing. Show-chrome or black finished heat shields with beautifully machined chrome billet end caps for a truly custom finish. Includes mounting hardware and removable baffles for simple installation. Power with social responsibility. Limited lifetime warranty.
