Hey guys, I got a black bear tune over the summer and I hate the current muffler I have. I would assume I can change the muffler to something else or even put the stock one back on without needing a new tune right? I'm not worried about loosing a few hp I just don't want it to be quieter when I'm towing etc.

Thank you

What is your current muffler? More than likely no tuning change needed.
