Give your new Toyota 4Runner or Land Cruiser a deeper exhaust note while improving clearance for off-road use with the MBRP 3-Inch High-Clearance Cat-Back Exhaust System.

Designed for the 2025-2026 Toyota 4Runner and 2024-2026 Toyota Land Cruiser with 2.4L gasoline engines, this MBRP cat-back combines a large 3-inch exhaust system with a compact high-clearance turndown exit that eliminates a conventional exhaust tip hanging behind the rear bumper.

MBRP tunes this system with its Street Profile, providing a deeper and more noticeable exhaust note while remaining appropriate for a daily-driven vehicle.

High-Clearance Overland Exhaust Design

One of the most important features of this MBRP system is its high-clearance turndown exit.

Instead of routing the exhaust all the way to a traditional tip behind the rear bumper, MBRP uses a compact turndown configuration designed to improve rear clearance.

This is particularly beneficial for 4Runner and Land Cruiser owners who use their vehicles for:

• Off-roading

• Overlanding

• Rock crawling

• Trail driving

• Camping

• Hunting

• Backcountry travel

• Vehicles with aftermarket rear bumpers

Removing the traditional rear exhaust tip from the departure area reduces the possibility of damaging the exhaust when descending ledges or navigating steep terrain.

3-Inch Cat-Back Exhaust

The system uses:

3-Inch Exhaust Tubing

The complete cat-back configuration replaces the exhaust system downstream of the factory catalytic-converter section while retaining the vehicle's emissions equipment.

The larger tubing and MBRP muffler configuration provide a more aggressive exhaust character than the factory system.

MBRP Street Profile

MBRP classifies this exhaust as its:

Street Profile

The Street Profile is designed to provide a deeper exhaust tone that is somewhat louder than stock without turning the vehicle into an excessively aggressive exhaust application.

This makes it particularly well suited for a 4Runner or Land Cruiser that serves double duty as both:

• Daily transportation

• Weekend trail or overland vehicle

The goal is a more noticeable and enjoyable exhaust note while maintaining the drivability expected from a modern Toyota SUV.

Choose ARMOR Lite or ARMOR Pro

MBRP offers this exhaust system in two material configurations, allowing you to choose based on budget, climate and intended vehicle use.

ARMOR Lite – S5344AL

Material: Aluminized Steel

ARMOR Lite provides the same basic exhaust configuration and MBRP sound profile at a lower cost.

It is an excellent choice for vehicles operated primarily in dry climates where extreme corrosion resistance is less important.

ARMOR Lite Features:

• Aluminized steel

• 3-inch tubing

• Street Profile

• High-clearance turndown exit

• Cat-back configuration

• 3-Year Warranty

ARMOR Pro – S5344304

Material: T304 Stainless Steel

ARMOR Pro is the premium version of this exhaust system.

T304 stainless steel provides significantly greater corrosion resistance, making it an excellent choice for vehicles exposed to:

• Snow

• Road salt

• Coastal environments

• Mud

• Water crossings

• High humidity

• Harsh winter conditions

MBRP backs the ARMOR Pro version with a:

Lifetime Warranty

For customers planning to keep their 4Runner or Land Cruiser long term or regularly expose it to demanding conditions, ARMOR Pro provides the highest level of material durability.

Same Configuration – Different Materials

Both versions share the same fundamental design:

S5344AL – ARMOR Lite

• 3-inch

• Cat-back

• Street Profile

• High-clearance turndown

• Aluminized steel

S5344304 – ARMOR Pro

• 3-inch

• Cat-back

• Street Profile

• High-clearance turndown

• T304 stainless steel

The primary difference is the material and warranty, allowing customers to select the version that best fits their budget and environment.

Ideal for the 6th-Generation Toyota 4Runner

This system is designed for the new 2025-2026 Toyota 4Runner with the 2.4L engine.

MBRP's current application data includes the 4Runner and is not limited solely to the TRD Off-Road trim.

This makes the system an excellent exhaust upgrade for compatible 2.4L 4Runner models where MBRP lists fitment.

Also Fits the Toyota Land Cruiser

MBRP also lists the same exhaust system for the:

2024-2026 Toyota Land Cruiser – 2.4L Gasoline

This cross-platform compatibility is important because Toyota's latest 4Runner and Land Cruiser applications share the compatible exhaust configuration used by this MBRP system.

Excellent Choice for Modified SUVs

The high-clearance design makes this MBRP exhaust particularly well suited to vehicles equipped with:

• Suspension lifts

• Larger tires

• Aftermarket skid plates

• Rock sliders

• Off-road rear bumpers

• Recovery equipment

• Overland equipment

• Roof racks

• Camping equipment

Rather than installing an exhaust with a large polished tip hanging below or behind the bumper, the turndown design keeps the exhaust tucked away from common trail obstacles.

ARMOR Lite vs. ARMOR Pro

Choose ARMOR Lite if:

• Value is the priority

• The vehicle operates primarily in a dry climate

• You want the MBRP sound and high-clearance design at a lower cost

• A 3-year warranty meets your needs

Choose ARMOR Pro if:

• Maximum corrosion resistance is important

• The vehicle encounters snow and road salt

• The vehicle is frequently exposed to water or mud

• You live near the coast

• You plan to keep the vehicle long term

• You prefer T304 stainless steel

• You want MBRP's Lifetime Warranty

How loud is this exhaust?
MBRP classifies it as its Street Profile, which provides a deeper exhaust note that is somewhat louder than the stock exhaust.
