Since i need a new muffler for my 2001 2.2L Cavalier, and reading up a bit, a simple project would be to use something like a Walker 56012 Resonator Assembly and just add a muffler to the end and that's pretty much it? There are no emissions standards so this overall should make my car quieter and sound smoother? I'd probably get a Walker Quiet-Flow muffler as well, but basically a shop would be able to do this all fairly easily?

Thanks
