The aFe Mach Force XP 3-inch SS Axle-Back Exhaust is a high-performance exhaust system designed for the BMW 135i models from 2008 to 2013. Constructed from durable 304 stainless steel, this axle-back setup features a 3-inch main tubing diameter and a resonance chamber to optimize exhaust flow. It delivers an aggressive and loud exhaust note, enhancing the vehicle's sound profile while increasing horsepower and torque. The system is engineered to improve overall performance by reducing exhaust gas temperatures and promoting better flow dynamics. Each unit is mandrel-bent for smooth bends and maximum flow, ensuring durability and consistent performance gains.

This exhaust system is a direct bolt-on upgrade for 2008-2013 BMW 135i models, fitting various chassis codes with no additional modifications required. It is intended for enthusiasts seeking a more aggressive sound and improved power output for street or track use. The kit includes the axle-back pipes and necessary clamps for installation, providing a straightforward upgrade path. Suitable for daily driving, spirited street driving, or track days, this system enhances both the sound and performance of the vehicle while maintaining OEM fitment and quality standards.

Overview

Mach Force XP 304 SS Axle-Back Exhaust System with Dual Rear Exit (49-36302-B) by aFe. With 3" Resonance Chamber. Exhaust System Type: Axle-Back. Exhaust Tubing Material: 304 SS. Main Tubing Diameter: 3". 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 Axle-Back 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. 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. 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 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. The team of engineers, machinists, production and sales people at aFe have many years of experience in their respective positions, and together work to ensure they produce the best automotive products on the market.
