shouldnt be a problem... some shops have different policies on pre-purchased parts, but at ours we'd always help someone out, especially since the only import style mufflers we carried sounded like ****, lol. Shop rates (price) varies from area to area per hour, so I can't tell you how much its going to cost, I'd give them a call, or let them take a look at your car to give you an accurate estimate.

 

I have my old cat in my garage.
