The only droney part of the rev range is about 2100-2350rpm That is where the most "drone" occurs. Im not bothered by it because Im usually below 2000rpm or far above it. I had this performed at a local exhaust shop, they welded a flange in place so the muffler could be swapped in a matter of minutes with basic tools, and it uses the stock muffler hanger. Cost was about $120 after tax.
what size tips (what kind) and what size piping ? love this video. makes me just want to do a muffler delete lol.
