I thought the fishtail dyna mufflers looked cool, so I picked up a set from a 1986 Dyna 1340, they are the shorter version, and also the california emissions, evidently, with the catalytic converter built in, they are like new, but was wondering if the cat in each one will be any problem with flow or with clogging up with soot. Any ideas about these mufflers? I am going to slice off the one mount block, and weld it to the opposite side and cover the area of surgery with the heat shield that came on the muffler. Should look cool, and sound good, I hope!
