First I ordered it on the 19th and was told it would be here on the 27th and I actually received it THE NEXT DAY, I couldn't believe it. After I removed and put the muffler back on, a major downside was that it was actually about 2/16" too big, causing my tape clips to not be effective. As far as that goes, I'll be welding it in the near future. As for the pipe with As for clamps, it sounds good instead of a silencer, so far I'm very satisfied.
