Borla cat-back exhaust system.

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. Tests have shown an exciting 41% increase in flow for dramatic improvement in power or fuel economy. 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.

A cat-back system replaces everything behind the catalytic converter and leaves emissions equipment in place.
