I have a 2011 zx6r with a TRC yosh slip on. I was wondering if someone makes a custom pipe to connect slip on to headers? or if i can buy headers and fit them on bike later on down the road.

The end goal is to remove that butterfly valve design and run strait to the headers. thanks

 

I'd check with a local muff shop that does custom pipe bending. OR, try Advance Auto, Auto Zone, etc, for a connector pipe in the correct diameter for a "spacer." Some of those auto places have a surprising amount of exhaust stuff in stock.
Welcome to the forums, BTW!! Aloha!!
Gear up; stay safe.

 

I had an 05 636r with the undertail exhaust system. Stock it came with the butterfly in the exhaust. I bought an aftermarket exhaust from Muzzy. It got rid of the butterfly stuff. It was just a slip on system. Sounded good and lightened it up a lot. Got rid of those cables and stuff. It added a little "stop" to the actuator. I havnt gotten up close and personal with the new ninjas yet. I always bought muzzy stuff for my crotch rockets. Dont know much about the yosh systems. Thought most aftermarket systems got rid of that butterfly stuff??

 

yosh does not offer that mid tube for the TRC? I have not explored that exhaust info yet.
