Part #: 49-48057-P

Overview

The aFe MACH Force-Xp 2.5-inch 409 stainless steel Hi-Tuck cat-back exhaust system is a premium performance upgrade designed specifically for Jeep Wrangler models from 2007 to 2018 and Jeep Grand Cherokee V6 models from 2005 to 2010. This exhaust system enhances your vehicle’s exhaust flow and sound quality while maintaining seamless integration with factory controls. It offers Jeep enthusiasts a perfect balance of aggressive exhaust tone and everyday drivability without compromising fitment or durability.

Engineered to improve throttle response and engine efficiency, the MACH Force-Xp exhaust features a high-flow muffler and mandrel-bent tubing that optimize exhaust scavenging and reduce backpressure. Its unique valve-controlled design allows drivers to switch between a smooth, quiet tone and a louder, more aggressive exhaust note, making it ideal for both street cruising and spirited off-road adventures.

Key Features

This cat-back exhaust system combines advanced engineering and premium materials to deliver a superior upgrade for your Jeep:

• Mandrel-bent 2.5-inch 409 stainless steel tubing for maximum exhaust flow and corrosion resistance
• High-flow transverse muffler designed to optimize scavenging and minimize backpressure
• Factory-style exhaust valve that integrates seamlessly with the vehicle’s original valve motor and performance modes
• Valve operation enables a smooth, quiet tone when closed and an aggressive, free-flowing sound when open
• Polished stainless steel exhaust tip featuring a laser-etched aFe POWER logo for a premium appearance
• 100% hand MIG welded construction for superior strength and leak-free performance
• Hi-Tuck design improves ground clearance and fits tightly under the vehicle for a clean, factory-like look
• Direct bolt-on installation with no cutting, welding, or modifications required

Construction & Design

The MACH Force-Xp exhaust system is crafted from high-grade 409 stainless steel, known for its excellent corrosion resistance and long-lasting durability in harsh environments. The mandrel-bent tubing ensures smooth, consistent bends that maintain the pipe diameter throughout, preventing flow restrictions and enhancing exhaust gas velocity.

The transverse muffler is engineered to maximize exhaust flow while tuning the sound to provide a balanced tone that is both aggressive and refined. The Hi-Tuck design routes the exhaust higher under the vehicle, improving ground clearance and protecting the system during off-road use. Each weld is performed by hand using MIG welding techniques to guarantee a precise, strong, and leak-free assembly.

Performance & Sound

The integrated factory-style exhaust valve allows you to tailor your Jeep’s exhaust note to your preference. When the valve is closed, exhaust gases pass through the high-flow muffler, producing a smooth, controlled sound ideal for daily driving and highway cruising. Opening the valve bypasses the muffler, unleashing a louder, more aggressive exhaust tone that enhances the driving experience and signals increased performance.

This system improves exhaust flow, which can contribute to better throttle response and engine efficiency. The combination of enhanced sound and performance makes it a perfect upgrade for Jeep owners who want both style and substance.

Installation & Fitment

The aFe MACH Force-Xp cat-back exhaust is designed for a direct bolt-on installation with no cutting, welding, or modifications required. It fits a wide range of Jeep Wrangler models from 2007 through 2018, including Rubicon, Sahara, Sport, Sport S, Unlimited, and special anniversary editions. It also fits 2005–2010 Jeep Grand Cherokee models equipped with V6 3.6L or 3.8L engines.

Installation can typically be completed with basic hand tools and does not require specialized equipment, making it accessible for experienced DIYers and professional installers alike.
