Look closely at the mid pipe, you will see a seam around the circumference. I cut mine with a plasma cutter. Be sure to mark around this seam in 3 locations BEFORE you cut to ensure accurate re-fit.
Once cut you have to remove 3 small tack welds from each end plate located inside the mid pipe. Simply remove inner baffling. When refitting align all 3 marks and plasma weld again. Heaps of difference in noise. I never measured the power difference on a dyno with just this mod, but with the usual mods and remus cans the difference in mid range and top end was significant.
Try this, remove your mufflers and leave the mid pipes on, start the bike and listen, hardly any difference. Now remove the mid pipes as well and re-start just out of the headers. That's how mush restriction there is in the mid pipes alone.
