1986-1991 Chevrolet Corvette (C4) 5.7L V8 Automatic/ Manual Transmission Rear Wheel Drive Coupe/ Convertible (EXCEPT ZR1).
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.
Tests have shown an exciting 41% increase in flow for dramatic improvement in power or fuel economy. That now famous, aggressive BORLA® growl and sexy look proclaim this block may be small, but it means all business – we guarantee it for a million miles!
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.
