If you are budget minded but want your stang to sound MAD. You might try out the new Summit Racing twin tube internal bypass mufflers. They are a fully welded muffler and aluminized. Part #SUM-639251. They are loud but not irritating and will talk back on downshifts. I had a set of Dynomax turbo mufflers but they were just to quiet, to deep and to mellow. Just didn't sound like a Mustang should.
