keeway rkv 125 exhaust fitment noise and low-speed running

I am helping with a keeway rkv 125 exhaust because the stock system is dented and the owner wants a cleaner sound without making the bike horrible in town.
I found this related page while comparing options: keeway rkv 125 exhaust. I wanted a practical discussion before ordering anything.
