It is the classic Borla Muffler for the C5 Corvette for those who want it a little quieter in the cabin at Highway speeds. The Borla C5 Corvette 5.7L LS1 S-Type II exhaust is for use on C5 Corvettes with Automatic and Manual Transmissions. This Borla C5 Corvette Exhaust features the Quad 4.25" x 3.5" Oval Rolled Angle Cut Tips and has been Dyno Tested to increase both Horsepower and Torque.
