For the PV2, my shop welded two pieces of pipe to the existing front and back pipes. Then they used two flanges and actually connect the PV2 to the pipes. He said he did it just incase I ever wanted to take it off, so it wasn't permanently on. I have to agree, if your looking for a quite ride, the PV is definatlly not for you. Although I listened to Analog's from the forum and he put a much smaller tip on his and it cut the sound by about half.
