Exhaust Systems

Large Bore Exhaust

Increase your Diesel's power and efficiency with aFe's large bore exhaust.  On its own or in conjunction with an intake or module, aFe's large bore exhaust is dyno proven to increase power and reduce EGT.

  Up to 100% more flow than stock!

aFe's Diesel exhaust systems feature free flowing 4" mandrel bent tubing and an 8" diameter 30" long straight through muffler that delivers a deep mellow sound.  aFe's exhaust systems are the perfect power producing complement to aFe's Magnum Force intake systems.
