Unleash the Power

Elevate your 1986-1991 C4 Corvette's performance and sound with the BORLA Performance Cat-Back System. Designed for the 5.7L V-8 engine, this premium exhaust system is crafted from aircraft-quality, high-performance austenitic stainless steel for durability and strength. It’s engineered for an effortless bolt-on installation and serves as a direct replacement for the stock system, which is up to 20 lbs heavier!

Inspired by the legendary C5/Z06 "Stinger" system, the BORLA Cat-Back features a 3" front pipe leading to a Y-pipe, splitting into two 2-1/2" pipes that exit on either side of the rear. Each side is equipped with a 10" x 5" round muffler, paired with your choice of sleek, polished tips—either a rectangular, rolled edge, angle cut (part #140082) or a round rolled angle cut phantom tip (part #140051).

Expect an impressive 41% increase in flow, delivering not only a noticeable boost in horsepower but also an improvement in fuel efficiency. The unmistakable BORLA growl and striking appearance turn heads wherever you go, proving that this V8 may be compact, but it means business.
