Tame exhaust drone and keep your SUV sounding factory-smooth with the Walker Quiet-Flow SS Exhaust Muffler Assembly 55469. This direct-fit muffler assembly bolts in as a replacement for the 2001-2003 Acura MDX and 2003-2008 Honda Pilot, with a 2" inlet (OD) and a 2" outlet (OD). See the "Vehicles it fits" section for the full engine-level application list.
- Stainless-steel body: 100% stainless-steel construction delivers longer life than typical aluminized mufflers, while an internal drainage system reduces moisture collection.
- Easy bolt-on install: Direct-fit replacement with factory-style routings, brackets and hangers, so no specialized fabrication or welding is required.
- 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.
- Premium acoustic control: OE-style louvered tubes lower noise levels and domed heads help reduce radiated noise for factory-style sound quality compared to straight perforated tubes.
Acoustic and flow tested, and backed by Walker's limited lifetime warranty and the exclusive 90-Day Safe and Sound Guarantee.
