So I was dead-set on getting a muffler delete my 06 OB xt, but being the 17 year old I am I had to ask for my Parents permission. Not surprisingly they vetoed that immediately. So, I've seen some videos online of people drilling holes in their exhaust or muffler and getting a deeper more aggressive sound.Is this something I could do to my car, and where would it best to do so. Any or all advice is appreciated.
