Hello, Husky.community! In case it is still interesting here is couple of words about how to remove DB-killer from TR650 EU style muffler and what is inside. I've deleted it in 2 steps by usig of smallest cut-ring of Dremel. It was done pretty easy because the thickness of stailess steel DB-killer is just 1 mm, with 1st cut in 30-40 mm depth and 2nd - in 10 mm (please see the photo in case it could be finaly uploaded: 2 yellow rings in "Before" part). The result: having still cat installed voice accent was moved from air filter pod-mod towards exhaust dretion and voice itself became more brutal, similar to what I have seen in: View: https://www.youtube.com/watch?v=qlLxkR8Z4Cc . Inside I've found quite big ball of fiberglass, removed it carefully and washed tube with solid amount of water from the side of cat. Now, the rear part of tube is free from spark arestor and no any spark were detected during the trial run (catalyst???).
