This 2.5" diameter BORLA Cat-Back system is designed for use on EcoBoost cars WITHOUT the Active Exhaust feature. It features Borla's aggressive ATAK sound with no drone inside the vehicle, and dual 4" round black chrome on T-304 stainless steel tips. Using BORLA Stainless Steel Polish p# 21499 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 carbon fiber tips are also available. If your car has 1 tip on each muffler and you want to upgrade it to 2 tips on each muffler (also known as quad tips), this is the system for you. It is designed to work with the quad tip (2 tips per muffler) Original Equipment (O.E.) Ford Valance ONLY. To install this system on a vehicle that came with one tip per muffler you will NEED TO BUY and install a different valance. Ford quad tip valance part numbers: With Parking Sensors = PR3Z-17F828-DA, Without Parking Sensors = PR3Z-17F828-CA. BORLA Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology 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 numerical control (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.
