But they made some very nice stuff. ...I'll know for sure soon..Those Dencos looked alot like em also seen one Dunstall 4 into one on a CB750 just one:silly:

Even though I've never seen one just like that my guess is MAC just from the shape of the megaphone.BTW, MC distributing sells MAC bike exhaust systems in Canada - did you buy it from a Canuck or someone near the border?

Close Illinois..

By the way, that is a HOOKER pipe. If I am not mistaken, HOOKER pipes came out on the Left side of the bike instead of the more common Right side. But I think on the KZ1000 they flipped it to the right after the second production run because of complaints. The simple way to find out which you have is to look at the mounting tab on the muffler. Hooker was easily spotted because the tip of the muffler had a "molded" end almost like a stock exhaust pipe.
