Borla S-Type cat-back exhaust for 1986–1991 Chevrolet Corvette C4 (5.7L V8, excluding ZR1) is a direct-replacement stainless system engineered for both manual and automatic cars. It uses a 3" front pipe that splits to dual 2.5" outlets, with 10"x5" mufflers and polished rolled-edge rectangular tips. Constructed from premium T-304 stainless steel with mandrel bends, the system increases flow substantially and carries Borla's long-term warranty.
