this fishtail pipe was 30 inches long. I had to cut a few inches off and cut the bracket off the front and cut the rear bracket shorter and drill a hole to mount it in the factory position. I also had to cut a few inches off the header pipe where the two come together. I don't have a torch or a welder so I had to make an angle cut on the header pipe to try to keep the fishtail even with the swing arm. it is mounted temporary right now. it has a gap that needs to be fixed. my friend is gonna fix and weld it for me. I put the factory plate over the connecting pipes. the header slides into the fishtail about three inches.

That is a sweet set up,I never had any luck keeping the pipe straight when I set mine up but I was using standard car pipes,it looks really good the way you have it. Are there baffles or just straight?

If you are not opposed to ugly you could cut a beer can and fill it out with gasket goo and clamp it all tight to set,that's what I did,looks like you are keeping it legitimate though.

It came with the baffle but it is not in it. The video does not do it justice on the sound. It is louder than the video shows.:D:ride:

I was thinking about that or a reducer with clamps or the reducer and welding. we'll see what I decide when things warm up again.

Reducer riveted should work very well but weld would be ideal,riviting is a pain any way.

I ordered the adapter to fill in the gap. It should be here this week.

Where did you find one?

I found it on ebay.

:D I got the adapter in Thursday and installed it Saturday . everything looks and sounds good. Took my wife for a ride about 20 miles round trip and topped off the tank. With our combined weight of around 300 lbs. we still got the gz250 up to 68mph with some throttle left to spare. Bike is running nice and smooth!:ride:
