No eBay APP ID and/or Cert ID defined in Kunena configuration

Not mine. NOS Mac on ebay for GPz1100, pretty sure it will fit the J, someone else surely knows how close for it and others.

When I bought my kz650 in the early 80s, it had a Yosh exhaust on it.
It had no baffle, so was a little loud. ;)
It got severly rusty over the years, so I bought a new Kerker.
Wish I had held onto the Yosh pipe, as I'm in need of an exhaust.

I have read this thread and cannot find any reference to primary tube diameter and length, which I have found to be more important than any measurement of the tail piece.
In 1982 I was putting my Z1 Superbike through AMA tech at Daytona. Ahead of me in line was Eddie Lawsons KZ1000.
I was running the Kerker Pro pipe that had 1 1/2" diameter tubes. Lawson was sponsored by Kerker and had a similar looking exhaust that was touted as their Pro pipe, but I measured 1 5/8" primary tubes. After trying in vain to buy one from Kerker, I took it upon myself to fabricate one...it worked great.
Those of you who have various pipes on hand now, please post up the outside diameter of the primary tubes.
