Borla is the pioneer of the catback exhaust system. The S-Type exhaust systems offer slightly more growl and volume than the standard Borla systems for those who want even more sound. Mufflers are engineered per vehicle for flow and volume offering the best sound and performance. Designed to fit behind your factory catalytic converter(s) so your vehicle will still be completely smog test legal. Constructed entirely of aircraft grade 304 stainless steel that won't rust or corrode, even after years of use in any weather. Smooth mandrel pipe bends ensure exhaust gases escape smoothly and quickly improving power, torque, and throttle response. Borla S-Type systems use all your factory hangers and rubber isolators, as well as new Accuseal clamps. Beautiful polished tips finish off the system and are sure to get attention. All Borla exhaust components are manufactured in the U.S.A.
