Cat-Back System, AFE MACH Force-Xp, 3" SS, 2016-19 ATS, 3.6L Twin Turbo

2016–19 ATS-V 3-inch "MACH Force-Xp" NPP Cat-Back Exhaust by aFe POWER®

Factory-style dual-mode valves retain exhaust control, and an X-pipe helps reduce drone.

The "MACH Force-Xp" system from advanced FLOW engineering (aFe POWER®) combines MIG-welded, mandrel-bent 3-inch 304 stainless steel tubing with two high-flow mufflers and an X-pipe. Four 4-inch tips are available in black or polished finishes. Its dual-mode valves reuse the vehicle’s original valve motors, which are not included. Applications: 2016–18 Cadillac ATS-V sedans and 2016–19 ATS-V coupes with the 3.6L twin-turbo V6 and NPP dual-mode exhaust. aFe POWER® reports dyno-tested gains up to 13 hp and 24 lb-ft. Exhaust components have a two-year limited warranty, with 90-day finish coverage.
