Probably don't have to but then you risk engine damage such as burned valves from running lean. Probably at the very least shorten engine life by not re-mapping. If you don't punch them all out you could probably use the TOR map.

Your pipes have baffles but not removable baffles. The baffles need to be cut, drilled, or knocked out. Not sure on the 09 but earlier had 3 or 4 baffles depending on the pipes. The 09 will also have a catalyst in the pipe you have to be careful not to damage if you are going to leave it in place. I have heard it is soft making it difficult to remove.

I learned all I need to know about life by killing smart people and eating their brains.
