2005-2010 Jeep Grand Cherokee WK Mufflers

Exhaust character on the WK Grand Cherokee is one of the most accessible things to change, and a muffler swap from 2005-2010 Jeep Grand Cherokee WK Mufflers does more for the truck's sound and presence than most people expect from a single bolt-on. The HEMI in particular responds well to a freer-flowing unit, going from the muffled note the factory exhaust was built around to something that sounds like the engine actually wants to be driven.

 

Inlet and outlet diameter need to match the WK's existing pipe sizing before ordering since adapter couplers add restriction and look unfinished under the truck, and the HEMI and 3.7L V6 use different pipe dimensions that require confirming the engine before selecting a replacement. Overall body length and clearance against the driveshaft and rear suspension hardware also need to be checked since the WK's undercarriage is tight enough that a muffler sized for another application won't fit without contact.
