BORLA(r) has once again set the pace in the Corvette performance exhaust world. This 2.5" diameter into the mufflers with dual 2" out Cat-Back(tm) system features S-Type Classic sound and dual 4" round polished T-304 stainless steel tips on each side. BORLA(r) Performance continues to prove why we've have led the aftermarket performance exhaust industry for over 40 years. BORLA(r) has an exalted heritage with Chevrolet performance vehicles. From the C5R LeMans winning Corvettes to privateers like KTEC, Pratt-Miller, Lingenfelter and Lou Gigliotti who have enhanced BORLA(r)'S knowledge of both the vehicle dynamics and the power-plant engineering. The C5 is a muscle car with a big powerful engine on a sophisticated, sexy chassis. BORLA(r) has always used the transfer of technology from racing to the street as a tool, and the C5, and C5 Z06 play right into that wheelhouse. With an experienced R&D staff, the BORLA(r) team has given the C5 the attention it deserves by rolling out several systems for the Corvette. Airflow management and exhaust engineering is a science with which BORLA(r) has more experience than anyone in the exhaust aftermarket. BORLA(r) offers a variety of options for the C5, and C5 Z06. Choose from several tip styles and muffler designs. BORLA(r) Performance Industries, the original pioneers of premium, high quality T-304 austenitic stainless steel (superior to 409 or aluminized steel) free-flow exhaust utilizes patented award and race winning technology to deliver quality, sound, performance gains and enhanced fuel economy — all with an easy bolt-on installation. Best of all, BORLA(r) street products carry an unsurpassed written million-mile warranty.
