• The hi-tuck tip design provides additional ground clearance at the exhaust exit during off-road use - compatible with all 4Runner trim configurations including those equipped with lifted suspensions.
• This is the Black tip version. The polished stainless steel tip version is aFe part number 49-36080-P.
• Does not require a CARB EO#. Legal for road use in all 50 states.

Features

• Constructed from 2-1/2 IN to 3 IN mandrel-bent 304 stainless steel tubing - premium 304 grade provides maximum corrosion resistance and long-term durability suited to the 4Runner's dual-purpose on-road and off-road mission.
• High-flow 304 stainless steel muffler with acoustically tuned expansion chamber delivers a deep, refined exhaust tone specifically calibrated for the 2025 4Runner's twin-turbocharged L4-2.4L engine, providing a more present and purposeful sound character than the factory exhaust.
• Hi-tuck tip design positions the exhaust exit higher relative to the bumper line, providing additional ground clearance during extreme approach and departure angles on off-road terrain without sacrificing exhaust flow.
• Single 4 IN diameter black 304 stainless steel exhaust tip with laser-etched aFe POWER logo provides a clean, aggressive underbody appearance suited to the 4Runner's rugged character.
• Up to +4 horsepower and +5 lb-ft of torque gains verified on aFe POWER's in-house DynoJet dyno, with improved throttle response across the RPM range.
• Direct bolt-on installation using factory-style flange and hangers - no cutting, drilling, or modifications required for a clean, complete installation.
• CAD-designed for precise, high-tolerance factory fitment specific to the 2025 Toyota 4Runner (N500) platform, covering all cab and trim configurations.
• 100% MIG welded for race-proven strength and long-term durability under repeated off-road shock loads, water crossings, and sustained high-performance use.
• aFe POWER exhaust systems are engineered and manufactured in Corona, California, USA.

Product Description

The aFe POWER 49-36080-B Vulcan Series Cat-Back Exhaust System is a precision-engineered bolt-on upgrade designed specifically for the 2025 Toyota 4Runner (N500 generation) equipped with the twin-turbocharged L4-2.4L engine - covering both the gas-only and hybrid configurations. The N500 marks a significant generational change for the 4Runner, replacing the legendary V6-4.0L with a modern twin-turbo inline-four that delivers stronger output and improved efficiency while shifting the exhaust note characteristics considerably. The factory exhaust on the 2025 4Runner produces a sound profile that, while refined, lacks the depth and presence that 4Runner enthusiasts associate with the nameplate's character. The aFe Vulcan Series cat-back addresses this directly with an acoustically tuned system purpose-built for the new powertrain.

The system is constructed from 2-1/2 IN to 3 IN stepped mandrel-bent 304 stainless steel, the premium stainless grade in aFe's exhaust lineup, chosen for the 4Runner's demanding underbody environment - trail dust, water crossings, rock strikes, and thermal cycling from repeated off-road use all demand a material that will hold up over years of service without surface degradation. The stepped tube diameter transitions from the catalytic converter outlet rearward, progressively expanding flow velocity in a controlled progression optimized for the twin-turbo L4's exhaust pulse character. The high-flow 304 stainless muffler incorporates an acoustically tuned expansion chamber that produces a deep, resonant tone without drone, adding genuine character to the 4Runner's exhaust without the harsh frequencies that can make smaller turbocharged engines sound strained.

The hi-tuck tip design is a purpose-built detail for off-road use - by positioning the exhaust exit higher and tighter to the vehicle body, it increases ground clearance at the rear departure point, reducing the risk of tip contact during steep descents, deep ruts, or low-speed rock navigation. This feature is designed for the 4Runner community that takes these trucks off the pavement on a regular basis. aFe POWER's in-house DynoJet dyno testing documents gains of up to +4 HP and +5 lb-ft of torque, with improved throttle response. The polished tip version is available as aFe part number 49-36080-P for owners preferring a mirror-finish look.
