Borla 11921CB 16-18 Chevy Camaro V8 SS AT/MT ATAK Rear Section Exhaust w/o Dual Mode Valves Ceramic Black
This Axle-Back system features the aggressive ATAK® sound awith no drone inside the vehicle. The 2.75" diameter (1 tail pipe on each side is 2.5") system has dual tips on each muffler assembly and will fit vehicles equipped with Dual Mode Exhaust (NPP) but it does NOT include NPP valves. It may be used with the dual tip lower bumper cover to convert a single, split rear exit to a dual split rear exit. By adding BORLA® X-Pipe with Mid-Pipes part number 60607 (WITHOUT AFM Valves), or 60610 (With AFM Valves) you can create a Cat-Back™ system for your Camaro SS Coupe. The X-Pipes with Mid-Pipes do NOT fit Convertibles. It features a durable high temperature black finish on dual 4" round T-304 stainless steel tips on each muffler assembly. Systems with polished T-304 stainless steel tips, and carbon fiber tips are also available. BORLA® Cat-Back™ and Axle-Back 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, high-quality austenitic 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.
