The Borla 11923 is an ATAK rear-section exhaust for the 2016-2024 Chevrolet Camaro SS 6.2L V8. The 2.75in diameter system is built for cars that left the factory with single tips and are NOT equipped with Dual Mode Exhaust (NPP) valves. It delivers the aggressive ATAK sound with no interior drone and finishes in single 4.5in round polished T-304 stainless steel tips on each muffler assembly. Adding Borla X-Pipe with Mid-Pipes 60607 (without AFM valves) or 60610 (with AFM valves) converts it into a cat-back system for the SS coupe; the X-Pipes with Mid-Pipes do not fit convertibles. Borla builds this system from premium T-304 austenitic stainless steel with patented straight-through, multi-core technology and ultra-smooth mandrel bends for maximum flow and a precise CNC-manufactured fit. It is handmade in the USA and backed by Borla's Million-Mile Warranty.
