Super Jet type of exhaust???

[engineman44]

ok so when i pulled my motor i noticed on this exhaust that there were 2 groves for what appeared to be O rings on the piece conecting the expansion chamber to the exhaust manifold .there curently is just a hose clamped over both pieces is that correct or should there be orings there to if so where can i order them ?(and type of exhaust )

There should be o-rings for sure.

 

[engineman44]

ok tried to look for some but i dont know the exact type of pipe and where too even look

 

[Matt_E]

You need Viton O-rings. You could try calling Factory Pipe and ask them what size o-rings their Type 9 or Type 4 uses. They may sell you some, but they'll be expensive through them.
You could also just measure what inside diameter you need (measure the diameter of the pipe at the deepest point of the o-ring groove in the manifold).
Then measure the thickness (the width of the o-ring groove).
Go to McMasterCarr's site and find the appropriate rings. They shouldn't cost very much.

A friend got a pack of them from Mcmaster Carr a couple weeks ago. He'd likely sell you a couple if you don't want to buy a whole pack (minimum order size).

ok so no one knows this exact type of exhaust???

has riva on exhaust manifold

looks like this one but page is curently blocked on my computer

Riva Drypipe or FPP Type 4 would be my guess.

pulled motor today so figured would just post this pic

no one has any link for these o rings or has taken previous measurments for them dont have a micrometer

What about this:

Or call Riva and ask them.

Is that a speedwerx chamber?
I have seen some dry pipe o-rings on ebay recently, if that helps.

 

[engineman44]

speedwerx is what i think it is

 

[engineman44]

its speedwerx i googled that and found them but who makes it is it there own company?

 

[engineman44]

no reply and wana get everything ordered

 

[DirtyJ]

I believe Speedwerx is there own company and are still in business. They dont make the watercraft parts anymore from what I understand, just dirt bikes and such. There is a member of this forum that works for them. Dont recall him username though.

 

[engineman44]

just called them very helpful i have 10 of them on the way with a new coupler this is the happiest day of my life well 2nd happiest first was getting the sj thank yall for the help

now that it has been figured out what type of exhaust it is whats the proper line routing for it ????

 

[Tyler Zane]

just like it was...

Weird, speedwerx chamber with a Riva manifold. Did you have exhaust leak problems?

 

[Matt_E]

Those manifolds are all the same.

 

[engineman44]

yes i did but also had no orings and broken coupler

 

[yamanube]

Those manifolds are all the same.

I don't think they are, I know speedwerx uses the Riva/FPP manifold but they cut the end off and weld on their own IIRC (and I thought they ground off "Riva"). I thought the SW pipe was smaller in diameter where it meets the manifold than the Riva/FPP.
