R&D pipe

[smithrookie]

Can anyone tell me what pipe this is? Are they any good?
Thanks

Never seen a chamber like that before, it almost looks like a Kawasaki 750 chamber that somebody custom welded a section onto to make it work in a superjet. As long as it fits, it should work fairly well, just as well as a superjet specific Coffman wet pipe (Rocket?), and definitely better than the stock exhaust.

yea I had never seen anything like it before and couldn't find any matching images... seller says is came out of a superjet.

Thanks

Kawasaki 750sxi Coffman exhaust...

Looking at it more though, it doesn't match either of those pictures except the way the chamber is routed...

Chamber sure looks like the Coffman Rocket I have in my 750sx with welded on tube to fit a SJ and an R&D manifold

But the coupler portion is in a different orientation.

I know it's a little late, but just came across this. It's an R&D seadoo HX 720 chamber modded to work on most boats.
