I had a Pro Pipe on my 03 Ultra and it was really good. Power was there, quality was there, but it started to get a little loud for me. But a very good pipe. On my 08 Ultra I decided to go with the DD Fat Cat with the stealth baffle.I will install next week after my 103 upgrad gets done, but I know a lot of folks that have the DD's so I am confiident it will be ok, at least as good as my Pro Pipe. For a better power curve, I reall like the 2 into 1 systems better. I have had the true duals and they were louder and had much less lower end. Good Luck.
