Description
86-91 Corvette 5.7L 8cyl S-Type SS Catback Exhaust
The premium, high-quality, T-304 Austenitic stainless-steel system is easy to bolt on, is a direct replacement for the much heavier (by some 20lbs.!) stock system.
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 assemblies use a 10″x 5″ diameter round muffler on each side of the vehicle, with 6.69″ x 3″ polished T-304 stainless steel rectangular, rolled edge, angle cut tailpipe tip at each split rear exit.
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!
BORLA pioneered the use of aircraft-grade 304 stainless steel tubing, a material with a higher content of carbon and nickel that won’t rust or corrode, for the automotive exhaust aftermarket. Each system is built from T-304 stainless steel to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
