I bought my exhaust parts from Thailand and they seem to work fine. I don't use the kickstand, but it's there. Given the width of the muffler, it's difficult to get the kickstand down while sitting on the bike. If standing along side the bike, it's no issue. I use the center stand almost all the time, so the side stand is mostly cosmetic for me.
I looked through my pictures and the one below is the only one that shows the side stand against the muffler. It touches the muffler, but I don't hear any rattling.
