Got my mid-muffler delete at Meineke for $175. Not just any Meineke shop, but one where the owner has a Charger Magnum with pipes. It sounded good but he wanted $450 for that setup. The MM delete was a little high by most people's experience, but I figured it was worth it to have a chain do it, plus they will figure out the pipe size. I think it's 2.5 inch but not certain.
