1979 KZ650B3 - exhaust question

Hello,
what options are out there for a 4-2 exhaust system? Or better anyone knows about a 4-4 ever built and available to purchase?

I don't think there are a lot of 4-2 or 4-4 options available.
There are some aftermarket mufflers, if your headers are in decent shape.
We'll have to wait for someone who has done this comes along.
Me, I usually go for a 4 into 1 exhaust system.
Delkevic being one, offering a Stainless steel exhaust, with a variety of mufflers.

 

I thought so.
About the 4-1 delkevic, should you have to re-jets the carbs?

I believe not with a standard air-box
