This 2.75" diameter True Dual Cat-Back™ system was developed for use on F-250 and F-350 Super Duty trucks with performance, sound, style and durability in mind. The system features our Hydroformed SwithFire® Technology. Completely eliminating the turbulent center intersection of a standard X-Pipe, BORLA®'S patented SwitchFire® design truly blends the combustion pulses from both sides of the engine for improved performance and a custom sound. The computer numerical control (CNC) formed mandrel bent pipes ensure maximum flow for horsepower and torque along with an accurate fit. The muffler is specifically designed to deliver the classic S-Type sound without any drone inside the vehicle. The system features a single 4.5" round black chrome on T-304 stainless steel tip on each tail pipe. 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. Systems with bright chrome on T-304 stainless steel tips, and black coated Brawler style T-304 stainless steel tips are also available. The system will NOT will fit trucks with dual rear wheels. BORLA® Cat-Back™ & Axle-Back 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. Only T-304 stainless steel which is superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability, is used in the construction of BORLA® systems, that allows us to give you a Million Mile warranty. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Give your Super Duty the power, performance, and sound it deserves, bolt on a BORLA®.
