B-pipe to waterbox connection??

[showmepro1200]

I suppose I can just cut the stock rubber exhaust pipe, but what does everyone do to make the connection from the B-pipe to the waterbox? Any sources or people out there with the proper size elbow?? Just wondering

Oh, and what jetting specs are recommended for a pair of 38s, Mod b-pipe, oem tunnel flame arrestor and ADA 35 cc head on an otherwise stock 701 motor?

Thanks :smile:

Hot products sells a replacement hose.

I used a 4 ply silicone elbow off of ebay , the reason i used it was it was delivered 2 days before daytona and only took 2 days shipping FWIW 2.5 to 2 inches reducer 90 degrees..... I better add to my reply that I have a alluminum water box also , I measured before i bought ,and it works for me .

the one I have is 45 degree.

Like this one... but I bet you can find it cheaper on ebay, or a turbo piping store online.

Yeah I think it's more a 45 degree turn than a 90 --- anyone know if Mcmaster-Carr carries these? (silicone, 45 degree reducer 2.5" x 2")

Or, does anyone have a used one they want gone? :wavey:

Thats a possible solution, BUT....

1 - the Yamaha oem hose is way bigger than the 2" end of the stinger on the chamber. It will scrunch down I hear but that's a lot of cranking on a clamp.

2 - I want to keep the stock parts to be able to put it back on if I ever sell the boat, have you priced out the exhaust hose from Yamaha??? Something like $80+ dollars.
