Factory Split Rear Exit Vehicles ONLY. This system features a black chrome finish on T-304 stainless steel tips. 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. Add adapter 60706 for crew cab standard bed (6' 7") 157" wheelbase vehicles. System features BORLA?'s Polyphonic Harmonizer Technology which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound to the BORLA? mufflers. The mufflers then enhance this sound to the character and volume appropriate for our Touring, S-Type and ATAK? systems. Replace the Polyphonic Harmonizer behind the muffler in the ATAK? system with muffler 60679 to attain the "S-Type" sound level (quieter than ATAK?). 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.
