BORLA Performance has once again proven why we’ve have led the aftermarket performance exhaust industry for nearly 30 years. BORLA has an exalted heritage with Chevrolet performance vehicles. From the C5R LeMans winning Corvettes to privateers like KEC, Pratt-Miller, Lingenfelter and Lou Gigliotti who have enhanced BORLA’s knowledge of both the vehicle dynamics and the power-plant engineering. The new C6 is a muscle car with a big powerful engine on a sophisticated, sexy chassis. BORLA has always used the transfer of technology from racing to the street as a tool, and the C5, C6 and Z06 play right into that wheelhouse. With an experienced RD staff, the BORLA team has given the Chevrolet mark the attention it deserves by rolling out several new systems for the Corvette. Airflow management and exhaust engineering is a science with which BORLA has more experience than anyone in the exhaust aftermarket. BORLA offers a variety of options for the C5, C6 and Z06. Choose from several tip styles and muffler designs. Cat-Backs and Rear Sections are available with either the highly popular “S-Type” muffler or the “Touring” muffler. The “S-Type” is a smaller, round muffler with a center-in/center-out configuration giving a more aggressive sound and higher flow. For those who prefer it on the milder side, we have the “Touring” muffler -- a larger case producing less aggressive sound. Some come with an assortment of tip designs. Part No. 140191 details: 3” X pipe assembly followed by a 3.00” left and right extension pipe. Connecting to the extension pipes are two 3” over-axle pipes followed by the rear muffler assembly which consists of two 3” muffler inlet pipes and two 5” diameter X 10” long round “S” style mufflers. Exiting each muffler is a 3” outlet pipe leading to a collector which splits into two 2” pipes. Connected to each pipe are the single, 4.25” diameter X 4” long, round, rolled edge angle-cut, intercooled split rear tips. RD Test Results show flows of up to 100cfm more than the factory exhaust (for a total flow of 1199 cfm @ 50” H2O). Weight Comparison: 44 lbs. while the factory system weights in at 71 lbs. Sound: 108.725 dba using SAE standard J1169 which is 12.1 dba louder than the factory exhaust. Horsepower/Torque Data: Using a Dyno Jet 248 Chassis Dynamometer, we have seen gains of up to 24 additional horsepower and 24 additional ft. lbs. torque.
