Product Description

The MBRP S5343AL is a 2.5" Armor Lite cat-back exhaust built for the 2004-2024 Toyota 4Runner 4.0L V6, featuring a high-clearance turndown exit designed to hold up to rough terrain and off-road use. Heavy-gauge aluminized steel tubing with fully sealed construction resists rust and stands up to debris impact from the trail.

All tubing is mandrel bent for maximum exhaust flow with no rippling in the bends, delivering a moderate street profile tone without crossing into aggressive territory. Every component is direct fit to the factory OEM hanger locations, and the kit includes all clamps and brackets needed for a bolt-on installation with no welding required.

Backed by MBRP's 3-year warranty, this Armor Lite system is built for 4Runner owners who want a durable, trail-ready exhaust upgrade with improved sound and flow at a value price point.
