The aFe Vulcan Series stainless steel cat-back exhaust is a direct-fit system for 2021–2022 Jeep Wrangler JL models and uses mandrel-bent 2½"–3" 304 stainless tubing for durability. It features a high-flow muffler for a deeper tone, an X-pipe merge to balance pulses and minimize drone, and factory-style pneumatic exhaust valves for dual-mode sound. The system is MIG-welded and uses factory hangers for bolt-on installation without cutting.
