BORLA® Axle-Back exhaust system 11951BC is designed to fit the 5.0L Mustang GT that is equipped with Active Valve Performance Exhaust. It features dual black chrome on T-304 stainless steel tips and the "S-Type" sound. Using BORLA® Stainless Steel Polish p#21461 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth. It fits both the coupe and convertible models. The straight-through and patented multi-core technology is designed 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.
Each system is built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit.
Best of all, BORLA® stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
