GoPro Hero 3+ with external mic taped to the rear number plate. Camera is on the passenger roll hoop with the standard gopro roll bar mount. Tried a few positions , but this seems best till I find a new one ! Hard to get a balance between both exhausts. Easy to get too much of one and it sounds like a single cylinder machine
Glad you got the GoPro sorted in the end. Great to hear the mods. I have a roll bar mount but never used it. The suction cup proved more versatile although I did initially use a safety line in case it let go. Go out and enjoy making the deeper potato potato noises with the new setup...
