I have read the MSR page on splitter mods and dump pipes a while ago. Found it while i was searching through the forums

If you buy a replacement dump pipe, do all TBEs have the centre pipe and dump pipe the same lengths so you can interchange? or would it be a hassle to fit, in which case it would just be better to go with a more expensive one with a better quality dump pipe with a splitter. Or do they just do the splitter mod, which looks like a piece of plate welded into the bellmouth?

Yeah i'd probably do the resonatorectomy too.

pmh - i have seen the dyno sheet on the verso site, its a bit wavey, is this just due to different dyno printouts/units or something? Torque drops off pretty sharply at around 4000 rpm.
