BORLA STINGER CAT BACK EXH (86-91) (C11000)

Borla has engineered a system made from stainless steel that reduces back pressure by 40%. Expect to gain 25-35 horsepower with their simple bolt on installation. This system connects to the rear of the catalytic convertor and replaces the existing exhaust system. The mellow throaty sound is worth the price of admission alone.
