Looking at the Yoshismura style 4 into 1 stainless system (on ebay) to put on my '79 cb650z. They are available for both the 550 & the 750. The exhaust port spacing (I'm told) is the same for the 550 as the 650 but what issues would I run into? mounting, gaskets, frame etc From what I've read the 650 is derived from the 550 but I wonder what major differences / challenges I may run into with this.
Has anyone been down this road, am I wasting my time? I tried searching here but didn't really get this info. Everything seems to point to the MAC system and I'm not crazy about getting one of those.
Any help would be great!!!
