Product details
Flowmaster introduces our Outlaw Extreme stainless steel cat-back exhaust system for the 2003-2024 Toyota 4Runner with the 4.0L engine. This system uses an Outlaw series muffler for a deep powerful sound and increased performance. 3.0-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and better durability. The system has a turndown style, dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps improve ground clearance and departure angle when you are driving in more extreme off-road situations. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty. Fits 2003-2024 Toyota 4Runner 4.0L.
