  • Improves performance
  • Lowers exhaust gas temperature
  • Flow bench and dyno tested
  • Welded hangers with swaged ends
  • Slotted and swedged ends
  • Premium quality band clamps
  • Backed by a 2-year limited warranty
  • Proudly made in the USA

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

DETAILS:

Give your Grand Cherokee a more aggressive look and sound with this MACH Force-XP Cat-Back system. Large tubing, a high-flow stainless steel muffler, and a dual resonated mid-pipe provide a deeper sound, without any drone when cruising.
