This FlowFX cat-back exhaust system is designed for all 2010-2020 Toyota 4Runner models with the 4.0L engine. Features include 409 stainless steel construction for added durability and 16 gauge 2.50 in. mandrel-bent tubing for free unrestricted flow. The compact round straight-through FlowFX performance muffler attaches behind the catalytic converter and delivers a moderate deep powerful sound while the mandrel-bent stainless tailpipe tucks up high in the undercarriage protecting it from being crushed when traversing rocky terrain. The system uses the factory hanger locations and is finished off with a 3.50 in. black ceramic coated 304 stainless steel tip embossed with the Flowmaster name. The kit includes detailed instructions and all hardware necessary for a quick and easy installation you can do at home. Covered by our Lifetime Limited Warranty.
