Thanks Ferio for the pictures.

Little confused now. I thought after looking at the information I and others posted that the Hatori 650 TUNED PIPE 60L (LONG) was supposed to be aprox. 15"+ long and the 700 pipe is 17"+ long or so as shown above. I also thought the 601 was the shortest chambered pipe in the group for short stoke .60's and high rpm props and measured 15"+. Perhaps I am missing something here. Did they change the overall length or length to the first chamber when they went to the ribbed style finish vs the older smooth ?

My pipes are the non-ribbed smooth pipes like Ferio posted. Wish I had an older and newer Hatori catalog with exact spec's to have for reference - can't find online. Anyone have a pdf. version with pictures and specifications of these pipes ?


Attached is a pic from an ad I found showing a guy selling a Hatori 650 pipe with his Hanno, doesn't look like Ferio's above more like the 15" spec I thought it was - only a picture however. I have a hatori that looks just like the one in the ad and measures 15-1/4" (confusing). Just search Hatori 650 and the ad will come up.

Also the other pic is the 700 pipe and specs right from HatoriUSA website and the pipe is 17" long.........
