I knew you were running 1-5/8 and often mentioned yes it was a compromise, but that they fit so nice and for (up to now) they were staying put. I’m no where near that level of performance but could probably use bigger diameter tubes as well. My issue is my exhaust is bent and positioned to fit the Dougs and unless an upgraded set sets exactly as they do I’d need to redo the head pipes. Not happening anytime soon:BangHead:
