B pipe coupler?

[yamanube]

What size is it (diameter)? Also what diameter is the end of the pipe and the inlet of the waterbox?

4" ID between the headpipe and chamber

How long are they good for and how likely are they to blow out? I have a used one that I got with my pipe that looks clean, no rips but am going on a long roadtrip and am always paranoid of things going wrong. Part of me says buy a new one and dont have to worry about it, another part says just rock it.

My hubby keeps a spare in the "parts box" that travels with us always.

I did the same for my dry, Ill do it on this pipe too.

What coupler does everybody use? On my dry pipe I went with one from www.hightempsilicone.com 3 ply coupler because it was a lot tougher than the FPP one and cheaper too. Do most just use an FPP coupler?

I use a standard FPP on my Limited Pipe, and it has held up well for two seasons now.

My Dry pipe blew out the coupler twice in the same season, until I bought a high temp one from here: http://www.boostcontroller.com/index.php?category=121

I would recommend buying an extra just in case though, as this seems to be a part that fails for people quite frequently.

You can get that from McMaster Carr. I have 12' of the stuff on the shelf so I have a life time supply. #5296K86
