Borla 86-91 Chevy Corvette C4 5.7L S-Type Catback System

Unleash the true potential of your classic 1986-1991 C4 Corvette equipped with the 5.7L V-8 engine (EXCEPT ZR1) with the BORLA® S-Type Cat-Back Exhaust System. Engineered to perfection, this Cat-Back™ system from BORLA® Performance Industries is designed for enthusiasts seeking a significant upgrade in both performance and sound for their iconic Corvette.

Compatible with both manual and automatic transmissions, this premium exhaust system is crafted from high-quality T-304 austenitic stainless steel. The direct bolt-on design makes it a hassle-free replacement for the heavier stock system, shedding approximately 20 pounds for enhanced agility and performance.

The system features a 3" diameter front pipe positioned just after the catalytic converter, leading to a Y-pipe that splits into two 2-1/2" pipes, each exiting on one side of the rear. The distinctive muffler and tip assemblies sport a dual setup, with 10"x 5" diameter round mufflers on each side and polished T-304 stainless steel rectangular tips measuring 6.69" x 3". The tips feature a rolled edge and an angle-cut design, adding a touch of elegance to your Corvette's rear aesthetics.

Extensive tests have revealed a remarkable 41% increase in flow, delivering a substantial boost in power and potential fuel economy. The BORLA® system not only delivers on performance but also introduces the signature aggressive growl that has become synonymous with the brand. This audacious sound profile, coupled with the sleek and sexy appearance, signals that your Corvette means serious business.

Race-bred technology, derived from BORLA®'s successful race programs, is the driving force behind this exhaust system. The C5-R Race Team's dominance at LeMans and the Bondurant Corvette program at the Bob Bondurant School of High Performance Driving are testament to BORLA®'s storied success in the world of racing. With a million-mile warranty, the BORLA® S-Type Cat-Back Exhaust System assures you of durability and uncompromising performance, staying true to the legacy of BORLA®, the most winning exhaust in racing. Upgrade your C4 Corvette and experience the perfect blend of power, performance, and the unmistakable BORLA® growl.
