aFe power introduces the MACH Force-Xp cat-back exhaust system for the 2005-2012 Toyota Tacoma with L4-2.7L engine. This cat-back exhaust is constructed out of 2-1/2 100% MIG-welded, mandrel-bent, stainless steel tubing for maximum flow. The smooth transition bends and free-flow stainless steel muffler allow for low turbulence, increasing horsepower, torque and improved throttle response. In testing, the cat-back exhaust system resulted in gains up to +9 horsepower and +10 lbs. x ft. of torque, as measured on our in-house dyno. Finishing off this exhaust is a 4 diameter black tip. The tip comes with a laser-etched aFe Power badge riveted on for an aggressive style.
