Vehicle Fitment:

1986-1991 Chevrolet Corvette (C4) 5.7L V8 Automatic/ Manual Transmission Rear Wheel Drive Coupe/ Convertible (EXCEPT ZR1).

Tips: Single Rectangle Rolled Angle-Cut

EXCEPT ZR1. BORLA® Performance Industries Cat-Back™ system for the celebrated 1986-1991 C4 Corvette equipped with a 5.7L V-8 engine has been engineered to work with either the popular manual transmission or the automatic. The premium, high-quality, T-304 Austenitic stainless steel system is easy to bolt-on, is a direct replacement for the much heavier (by some 20lbs.!) stock system.

A 3″ diameter front pipe is mounted just after the catalytic converter leading to a Y-pipe, which splits into two 2-1/2″ pipes exiting on each side of the rear. The muffler and tip assemblies use a 10″x 5″ diameter round muffler on each side of the vehicle, with polished T-304 stainless steel rectangular, rolled edge, angle cut tailpipe tip at each split rear exit.

With race-bred technology that has been transferred from the many successful BORLA® race programs, it was no accident that this BORLA® system has won several major Corvette exhaust shootouts. Included in this great and storied past are such famous efforts as the C5-R Race Team that has dominated LeMans along with the Bondurant Corvette program at the Bob Bondurant School of High-Performance Driving. Only what you would expect from BORLA®, the most winning exhaust in racing.
