Walker Exhaust Exhaust Muffler P/N:18973

Quiet your Jeep's exhaust and route spent gases with the Walker SoundFX Direct-Fit Exhaust Muffler 18973, a bolt-on replacement muffler built for the 1999–2001 Jeep Grand Cherokee. It carries a 2.25" inlet (ID) and a 2.25" outlet (ID) and drops in like the original — see the Buyer's Guide tab for engine-specific applications.

• Aluminized steel construction: made with 100% aluminized steel for longer service life compared to low-carbon steel, and an internal drainage system that helps reduce corrosion.
• Built to last: internal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion, while spun-locked heads and OE-style spot welds add stability.
• Factory sound: louvered tubes help reduce radiated noise for factory-style sound quality compared to straight perforated tubes.
• Easy to install: a direct-fit, bolt-on design with pipe routings, hangers and brackets styled like the OE pieces, so installation doesn't require specialized fabrication or welding.

Designed and tested to extend muffler life, the SoundFX 18973 delivers a quality appearance and favorable acoustics as a direct-fit replacement.
