Muffler worked well and happy with purchase
Great price compared to other mufflers. Was packaged well and delivered in a timely manner. My husband ordered this muffler for an older Jeep Grand Cherokee and didn't have any issues with it fitting.

A good value
This resonator fit as it should, though in my case I replaced everything down stream of it with other Walker parts. It would have been challenging to reuse the downstream parts and replace just the resonator due to where mine rotted through. The downstream end is sized so the original pipe will slip inside, but you need to be sure you have enough length Does not include hardware, gasket or a clamp to be sure to have those on hand. It arrived quickly after I ordered it (2 days) and was priced competitively. Packaging was just a box, but the part survived its journey with no signs of damage.

The resonator was the wrong one. Not the fault of Walmart, but the Manufacturer. No problem because it is returnable.
