The aFe Vulcan Series cat-back exhaust for the 2025 Toyota 4Runner is constructed from mandrel-bent 2.5–3.0-inch 304 stainless tubing with a high-flow muffler and a 4-inch black stainless tip. This direct bolt-on system uses factory-style flanges and hangers for installation without cutting, features a hi-tuck tip for added clearance, and is fully MIG-welded for strength while delivering a deeper exhaust tone.
