still looking for a good compromise between nice sound and not too loud pipes for a 99 softail. I'd like to keep the stock headers and fit slip ons. I have screaming eagle at the moment but don't like the sound, from what I can read, Khrome werks 3 inch seems to be adequate, however, it says they fit 2007 and later models. My question is , can these mufflers still fit a 1340 , providing I can weld an attachment on it, or will they just not fit on the head pipes ?

07 pipe is 1 3/4 inch.

S&S tapered turbos are right up there in the slip on choices.
