Walker Exhaust Exhaust Muffler P/N:21640

Tame exhaust drone and keep spent gases flowing with the Walker Quiet-Flow SS Exhaust Muffler 21640, a direct-fit bolt-on replacement for the 2002-2004 Jeep Grand Cherokee. It routes through a 2.5" inlet (ID) and a 2.25" outlet (ID), and installs using OE-style brackets, hangers and pipe routings, so no specialized fabrication or welding is required.

• 100% stainless-steel construction: corrosion-resistant and built to last longer than aluminized mufflers, with an internal drainage system that helps reduce moisture collection.
• Built to last: internal partitions and mechanically joined tubes let the muffler expand and contract through temperature changes to minimize distortion, while spun-locked heads and OE-style spot welds add stability and service life.
• Premium acoustic control: OE-style louvered tubes lower noise levels and OE-style domed heads help reduce radiated noise for factory-style sound compared with straight perforated tubes.
• Design validated: acoustically and flow tested for OE-style sound.

Backed by Walker's limited lifetime warranty and exclusive 90-Day Safe and Sound Guarantee. See the Buyer's Guide tab for engine-specific application details.
