Hey guys, is there a flange adaptor available from the stock 3bolt zx2r exhaust to a standard pipe so I can fit a slip on?
Never found anything locally in my time searching while I owned one. I did find a suitable exhaust on Aliexpress, but the link is long dead now. I have seen some ZXR headers where people have chopped down the inner protruding section and bolted on a new aftermarket pipe. I believe Honda MC22 style is closest fit, but it might require the holes to be enlarged, or they may be in the wrong position etc. The end of the header is quite larger in diameter so finding an exhaust may be difficult. Universal in the correct diameter may work, but you need somewhere to hook the retaining springs. I would suggest that Kawasaki use the same joining flange across multiple models. Once you have the diameter, you may find something from another model that fits. My suggestion is ZXR400 or earlier ZX6R/7R/9R models. ZXR750 too.
