BORLA® PERFORMANCE introduces a new system for the celebrated 1986-1991 C4 Corvette equipped with a 5.7L V-8 engine. BORLA® has engineered this Cat-Back™ system to work with either the popular manual transmission or the automatic. The high quality, ausinetic stainless steel system is easy to bolt on, is a direct replacement for the much heavier (by some 20lbs.!) stock system and is based off the big brother C5/Z06 system known as the "Stinger". 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 assembly use a 10"x 5" diameter round muffler on each side of the vehicle, with your choice of a polished rectangular, rolled edge, angle cut tailpipe tip at each split rear exit (part # 140082) – or a polished round rolled angle cut phantom tip at each split rear exit (part #140051). 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 new 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.

BORLA is committed to providing world-class exhaust products which surpass the expectations of our customers. To that end, our facility is complete with a state-of-the art test and development center where we are continually improving our manufacturing efficiency and standards. We have pioneered a variety of improvements in the design of performance exhaust systems. Alex Borla currently holds several US patents for innovative exhaust system technology, and the company has won numerous "Best New Product" awards in the industry. Every BORLA Cat-Back™ system, Header and Rear Section is made from austenitic stainless steel (superior to 409 or aluminized steel) employing mandrel-bent tubing, all-welded construction, and is designed for accurate fit and easy installation. Nearly 30 years experience and special merge collector technology provide the ultimate in power and endurance.

The performance advantages of a BORLA are widely recognized. The top engine builders in the racing world rely on BORLA exhaust for maximum performance. In fact, BORLA is at the forefront of the movement toward responsible racing with our full line of patented, award and race-winning racing mufflers that not only maintain a race engine’s power, but in some instances actually add power. This technology is incorporated into BORLA exhaust for the street, providing 7-10% increased horsepower and torque when you plant your foot, and improved gas mileage at cruising speeds.

BORLA exhaust is built of aircraft-quality austenitic stainless steel -- stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show. Coating techniques, such as aluminizing, can somewhat prolong the life of mild steel, but coatings suffer at the weld points. And, comparing aluminized steel to T-304 stainless steel is like comparing gold-plated metal to solid gold! T-304 stainless steel has the highest chromium content, making it the most resistant to corrosion and therefore the most desirable material for a long-lasting exhaust system. Note: Only the flanges are not stainless. In our twenty-year experience, we have found the 3/8"--1/2" flanges are so thick they will never affect the performance or longevity of the system.
