2018–2025 Jeep Wrangler 2.0L Turbo / 3.6L V6

Part #: 49-48070-1B

Overview

The aFe MACH Force-Xp Hi-Tuck Axle-Back Exhaust System is a premium upgrade designed specifically for Jeep Wrangler models equipped with the 2.0L Turbo inline-4 or 3.6L V6 engines from 2018 through 2025. This bolt-on axle-back system replaces the stock muffler assembly with a more efficient and aggressive setup that enhances exhaust flow, sound, and overall performance without sacrificing ground clearance.

Ideal for Jeep enthusiasts who demand improved throttle response, increased horsepower and torque, and a commanding exhaust note, the Hi-Tuck design protects the exhaust system during off-road adventures by providing extra clearance over rough terrain. This system is a cost-effective solution that delivers both functional and aesthetic upgrades while maintaining factory mounting points for a hassle-free installation.

Key Features

The aFe MACH Force-Xp Hi-Tuck Axle-Back Exhaust offers a range of advanced features engineered to optimize performance and durability:

• Constructed from 2 1/2" mandrel-bent 409 stainless steel tubing for improved exhaust flow and reduced turbulence
• Rear exit with a removable 3 1/2" metallic black clamp-on stainless steel tip for a sleek, aggressive finish
• 100% hand MIG-welded joints ensure race-proven strength and long-lasting durability
• Utilizes all factory hanger locations with OE-style bayonet hangers for a secure, vibration-resistant fit
• Designed to replace the stock muffler assembly while retaining the factory front resonator pipe
• Produces a powerful, aggressive exhaust tone that unleashes the engine’s full potential
• Fits both 2-Door and 4-Door Jeep Wrangler JL models equipped with 2.0L Turbo or 3.6L V6 engines

Construction & Design

This axle-back exhaust system is expertly crafted from durable 409 stainless steel, known for its corrosion resistance and strength under high-heat conditions. The 2 1/2" mandrel-bent tubing maintains consistent diameter throughout bends, minimizing flow restrictions and turbulence to maximize performance gains. The system is fully hand MIG-welded, providing superior joint integrity and longevity compared to robotic welds.

The Hi-Tuck tip design is engineered to tuck the exhaust outlet higher than stock, reducing the risk of damage during off-road excursions. The clamp-on 3 1/2" metallic black tip not only adds a refined aesthetic but is also removable to increase clearance when needed. OE-style bayonet hangers secure the exhaust in place, preventing movement and wear even under high vibration and heat.

Performance & Sound

By replacing the restrictive stock muffler with a more free-flowing axle-back system, the aFe MACH Force-Xp enhances exhaust scavenging, resulting in improved horsepower, torque, and throttle response. The system’s design leverages the factory front resonator pipe to maintain a balanced sound profile while delivering a deeper, more aggressive exhaust tone that commands attention without excessive drone.

Installation & Fitment

The aFe MACH Force-Xp Hi-Tuck Axle-Back Exhaust is a direct bolt-on replacement that uses all factory mounting points and hangers, ensuring a straightforward, no-modification installation. The OE-style bayonet hangers maintain a stable pipe location, preventing sagging or rattling over time. This system fits both 2-Door and 4-Door Jeep Wrangler JL models from 2018 through 2025 with either the 2.0L Turbo or 3.6L V6 engines.
