System features S-Type Classic sound and polished T-304 stainless steel tips. Borla Performance has created quite a buzz with Vette owners! This incredibly popular 2-tip Cat-Back (PN140017 - dubbed the ?Stinger? on the Internet) features "S-Type" mufflers, giving a more aggressive sound. Borla offers a variety of options for the C5, and C5 Z06. Choose from several tip styles and muffler designs. Cat-Back? and Axle-Backs are available with either the highly popular ?S-Type? muffler or the ?Touring? muffler. The ?S-Type? is a more aggressive sound. For those who prefer it on the milder side, we have the ?Touring? muffler with a less aggressive sound. Across the country engine builders, Corvette shops and enthusiasts have proclaimed the ?S-Type? by Borla as ?the system no one can beat?. Borla has once again set the pace in the Corvette performance exhaust world. Others only wish they were genuine Borla. The horsepower is incredible, but the Borla growl similar to a NASCAR backing off for a hard turn at Daytona is the part that puts a smile on everyone?s face. It just says POWER.
