aFe POWER's new Mach Force-XP series cat-back exhaust system for your Toyota 4Runner with the V6-4.0L engine will get you there with speed and style. Designed from 2-1/2" & 3" mandrel-bent, 304 stainless steel, this exhaust system offers greater flow to deliver more torque and horsepower than the factory exhaust. This 4-piece designed cat-back system utilizes a less-restricting, high-flow, muffler to improve your 4Runner's performance while maintaining a deep, smooth tone. 100% hand MIG-welded by certified craftsmen for proven quality and durability, the Mach Force-XP exhaust system includes a 4" x 12" polished resonated exhaust clamp-on tip to give your 4Runner a clean, finished look.

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 100º, 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
