Is there cutting involved when switching the stock exhaust system for the performance exhaust system? Or, is it just a bolt off/bolt on install? I am really on the fence of whether to get the Performance exhaust. Install cost at the dealership is about another $165-200. Just wanted to know how difficult the install is. Thanks.
