all of them are going to preform about the same. I have a supertrapp IDS2 on my 400ex and Foreman 400 and really love them. Out of all the ones you mentioned, the supertrapp is the "tunable" one because it has disks. Add more for more power and noise. I run 12 in both. Also, I think the supertrapp is the best sounding pipe out of the ones you mentioned and probably the cheapest...aluminum too so its real light and no rust.:D

i have a graydon proline on my blaster and i love it. it is a low end pipe though. im not sure how good the 4-stroke graydon's are or if they are low end or top end pipes. you would need to consider which range you want. you could also get an all around pipe that would give you gains in all RPM ranges.
