Well, I got fed up of trying and turned them into... short cannons!
Wow, there is indeed a huge increase from one baffle out to two. Not sure I love the sound, compared to my long TORs. Will need more riding to compare. Since the cat is still in, I guess it helps in attenuating the louder thumping of the TORs, it is a bit muffled with the 2-baffle-out-now-short-cannon-used-to-be-tapered pipes.
Would love to try something else, but offerings are minimal in the part of the world I live in.
Cale, I guess your friend went to other route and gutted your pipes from the the other end.
