The aFe Mach Force XP 409 stainless steel cat-back exhaust system is designed to enhance the performance and sound of the Ford F-150 Raptor models from 2017 to 2018. Featuring a dual Y-merge configuration and a split rear exit, this exhaust system is constructed from mandrel-bent 409 stainless steel tubing, with diameters ranging from 3 inches to 3.5 inches. It delivers an aggressive and loud exhaust note while increasing exhaust flow, which results in more horsepower and torque. The system also helps lower exhaust gas temperatures, contributing to improved engine efficiency and durability. Each system is dyno-tested by aFe to ensure maximum performance gains, making it a reliable upgrade for enthusiasts seeking both sound and power enhancements.

This cat-back exhaust is a direct bolt-on replacement for the stock system on compatible F-150 Raptor models within the specified years. It is intended for use on trucks that require a performance upgrade for street or off-road driving, providing a more aggressive sound profile and improved exhaust flow. Installation involves replacing the factory exhaust with the included mandrel-bent tubing and dual exit tips, offering a straightforward upgrade process. The kit includes all necessary components for installation, making it suitable for enthusiasts looking to boost their vehicle’s performance and sound characteristics without extensive modifications.

Overview

Mach Force XP 409 SS Cat-Back Exhaust System with Split Rear Exit (49-33094-B) by aFe. With Dual Y-Merge Assemblies. Exhaust System Type: Cat-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 3" to 3.5". Exhaust System Sound: Aggressive / Loud. Get increased exhaust flow, more horsepower and torque, improved performance and lower exhaust gas temperatures with the aFe Mach Force XP Exhaust System. aFe dyno tests every system for maximum gains, and constructs them from mandrel-bent stainless steel for maximum flow and long-lasting durability.

A performance exhaust system is one of the most common ways of improving a vehicle's operation. The theory is simple; just reduce restriction to increase exhaust flow and you gain power. But all exhaust systems are not created equal; in reality there's more to it than just selling some sewer pipe sized tubes.

aFe tests its systems on the flow bench and the dynamometer to determine the right pipe size and muffler construction. Then they mandrel bend the pipes to ensure they maintain their shape and size throughout the entire length, to provide smooth, unrestricted airflow. Tubes that are not mandrel bent can lose up to 20% of their diameter in sharp bends. Some systems also include a straight muffler delete pipe if a more aggressive sound and maximum flow is desired. A typical aFe system will increase exhaust flow by up to 29% and lower EGT (Exhaust Gas Temperature) by up to 100 , with a corresponding improvement in power and performance.

But performance is only part of the equation. A quality exhaust system should be easy to install and made to last. The muffler and all pipes of the Mach Force XP system are constructed from durable 409 stainless steel. To ensure a tight seal, slotted and swedged ends are used whenever possible. When used with the supplied premium quality band clamps, the tightest, leak-free seal is the result. Every hanger is thoroughly welded on each side to ensure a strong attachment and the hangers also feature swaged bayonet ends to lock in place once installed.

aFe (Advanced Flow Engineering, Inc.) manufactures performance products for late model cars, light trucks and SUVs. The company was founded in 1999 with an initial concentration on high performance air filters. Since then, the company product line has broadened to include cold air intakes, fluid filters, exhaust systems, intake manifolds, intercoolers, programmers, differential covers, transmission pans and throttle body spacers.
