Borla S-Type Cat-Back TM & Rear Section exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive Borla Sound of Power respected by motoring enthusiasts everywhere.
From the design characteristics of the inner cores to the amount of sound-absorbing composite filament, all specifications of Borla exhaust systems are tuned on a vehicle-by-vehicle basis for an optimum blend of performance and sound. Combined with an unrivalled Million Mile Warranty, distinctive motorsport styling, easy bolt-on installation and enhanced fuel economy, the world’s most winning exhaust continues to lead the industry it founded over 30 years ago.
Borla exhaust systems are built of aircraft-quality austenitic stainless steel - stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show. T-304 stainless steel has the highest chromium content, making it the most resistant to corrosion and therefore the most desirable material for a long-lasting exhaust system. Borla engineers and manufactures all their exhaust products in the USA and back their street exhaust systems with a Million-Mile Warranty.
Borla's latest engineering advancement is the ATAK system - Acostically Tuned Applied Kinetics technology which allows a very high volume without drone and distortion. Borla engineers manage the sound waves inside the exhaust to produce an exhaust note that maintains its tone as revs rise. With ATAK, the sound output is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output. This exclusive technology produces the highest available dB (decibel) levels in the Borla street-legal lineup, and is designed for high-performance purists who prefer exhaust notes over their stereos.
