Factory Split Rear Exit Vehicles ONLY. Add Adapter 60706 for Crew Cab w\/Standard Bed (6' 7\") 157\" WB vehicles. This BORLA® system has a valve simulator to prevent the Check Engine Light from coming on. The 3.5\" into dual 2.75\" system features the aggressive ATAK® muffler and 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 with no drone inside the vehicle. Replace the Polyphonic Harmonizer behind the muffler in this ATAK® system with muffler 60679 to attain the S-Type sound level (quieter than ATAK®). This system features dual 3.5\" round black chrome  on T-304 stainless steel tips on each tail pipe. Installation REQUIRES removal of the Factory Valance 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. Systems with bright chrome on T-304 stainless steel tips, carbon fiber tips, and systems that reuse the original equipment tips are also available. 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.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEXCEPT ZR2 \u0026amp; AT4X models.
