The rule of thumb is, if the mods(changes) came after the cats no new tune needed.
Its when you get into long tube headers and stuff that you need a new tune. So as long as you just stuck a maggie muffler on then you are good to go. |

Also, high flow cats (or *AHEM* removal of the rear cats) will be grounds for a new custom tune. Of course, CAIs, long tubes headers, and even some shortys will require retuning as well.
Take care.
