HansO,
haha please don't apologize... I don't know if you remember, but I ended up PM'ing you and you helped me with a good tune for my R3T. I didn't physically remove the secondaries, but you opened them in the tune and the bike runs very well. It was a touch rich until I removed the baffles from my stock pipes and added a high flow K&N underseat, which evened things out. I'm good for now. I appreciate your follow up.
@IMFASTTOO, there don't seem to be plentiful options for R3T's in the full exhaust system department... Jardines and D&D only swap the cans and remove the CAT's, but don't replace the header pipe.
