MBRP S5344304 Armor Pro 3-Inch T304SS Turndown Cat-Back for 25-26 Toyota 4Runner

Vehicle Fitment

• 2025-2026 Toyota 4Runner (2.4L Turbo I4 / 2.4L i-FORCE MAX Hybrid, All Trims)
• 2024-2026 Toyota Land Cruiser (2.4L Turbo I4 / 2.4L i-FORCE MAX Hybrid)

Fitment Notes

• 2.4L turbocharged engine only (i-FORCE and i-FORCE MAX) - does not fit the previous-generation 4Runner with the 4.0L V6 (see S5343304 for 2004-2024 4.0L V6 fitment)
• Direct bolt-on installation using factory OEM hanger locations - no cutting or welding required
• Single rear high-clearance turndown exit - exhaust routes downward before the bumper, eliminating a visible rear tip and significantly increasing underbody clearance over a standard side or rear exit
• Designed specifically for the 6th-generation 4Runner's platform geometry and suspension articulation demands
• This is a cat-back system - does not replace, modify, or affect any emissions control equipment

Features

• Constructed entirely from T304 stainless steel - MBRP's most corrosion-resistant material, suited for all climates including mud, snow, salt, and sustained off-road use
• Smooth mandrel-bent 3-inch tubing improves exhaust flow over the factory system for improved throttle response and reduced backpressure
• Single rear high-clearance turndown design positions the exhaust exit high and tucked away - maximizing ground clearance underneath the 4Runner for rock crawling and technical terrain
• Street Profile sound tuning delivers a deeper, more satisfying exhaust tone over stock without aggressive volume or highway drone
• Dyno-tested and jig-manufactured for dimensional accuracy and consistent OEM-level fitment
• Bolt-on installation uses factory OEM hanger locations - installs without drilling, cutting, or welding
• MBRP Lifetime Warranty included with T304 stainless steel construction

Product Description

The MBRP S5344304 is an Armor Pro cat-back exhaust system purpose-built for the 2025-2026 Toyota 4Runner and 2024-2026 Toyota Land Cruiser equipped with the 2.4L turbocharged i-FORCE or i-FORCE MAX engine. Constructed entirely from T304 stainless steel with smooth mandrel-bent 3-inch tubing, this system is built to the exacting demands of a serious off-road platform - offering maximum corrosion resistance and long-term durability in the kind of extreme conditions the 4Runner is designed to conquer. The single rear high-clearance turndown configuration routes exhaust downward and tucks the exit point high and out of harm's way, providing meaningful clearance gains for rock crawling, trail articulation, and obstacle navigation where a traditional rear-exit tip would be at risk of contact.

Street Profile sound tuning gives the new 6th-generation 4Runner a deeper, more characterful exhaust note under acceleration while maintaining a composed, drone-free character at highway speeds. Installation is fully bolt-on using factory OEM hanger locations - no cutting, welding, or drilling required. This system is for 2.4L-engine 4Runner and Land Cruiser models only and does not fit the previous-generation 4.0L V6 4Runner. Backed by MBRP's Lifetime Warranty.
