I'm wanting to put a new muffler into my 03 Expedition that would have some more noise/rumble to it, but am struggling on where to find something that is large enough to replace the stock muffler. It would be great if someone knows where to look.

Thanks,
Kyle

 

You can pick up a Walker cat back system for less than $300 that sounds great or just replace the muffler and add a few extension pipes that are available at most auto parts stores.
