The aggressive ATAK voice with no interior drone for the 2016-2024 Camaro SS. This 2.75in rear-section system (one tail pipe per side is 2.5in) carries dual tips on each muffler assembly and fits cars with Dual Mode Exhaust (NPP) valves, though the NPP valves are not included - add adapter kit 60605 if needed. Dual 4in round T-304 stainless tips wear a durable high-temperature black finish. Add X-pipe mid-pipes 60607 (without AFM) or 60610 (with AFM) to build a full cat-back on the SS Coupe.
