Anyone know what kind of pipe this is?

[Big Kahuna]

uh, I would not necessarily call that matched up. The flange on the stock pipe attacheds to the headpipe, then the rubber boot goes over and acts like a waterjacket.

 

[Big Kahuna]

Either way, that stock manifold is very inefficient.

 

[yamanube]

These are two completely different chambers, the last one I posted was just some food for thought for the guys talking about a chamber that attaches to the stock manifold. I do not own that part nor do I know anything about it.

Either way, that stock manifold is very inefficient.

The B pipe manifold is hardly better.

 

[Big Kahuna]

Gotcha. Less Restriction......... But it works..............

 

[Ducky]

Im thinkin that chamber is an SXR wetpipe chamber variation. Dont think itll work on a yamaha headpipe.

 

[Big Kahuna]

The mounting flange is the same size...... There were some custom chambers done for X2's and Blasters that would have used this shape.

Thanks?

I wasnt being insulting. I got a chuckle because in one post you basically said
no way it could work
then followed it up with
heres a picture of it working

 

[Nottjbarlow]

alright, alright... you guys I'm done pulling your chain.

I've been wanting to make this for quite some time now and I was curious on what you guys thought if I didn't say "look what I made".

I've always wanted to make an expansion chamber like this so I figured I'd give it a try and you've seen the finished product.

Also just so no one thinks I'm BS-ing here's proof.

Very cool! How does it run?

 

[Nottjbarlow]

Its of similar shape to the limited chamber but about 20% larger body.

After I put some hard hrs on her I'd like to cap the end and convert it to center bleed style then run it for a comparison.

HA!!! Got em............. Got em.

 

[Nottjbarlow]

^^ not me...cool tat tho^^

[Nottjbarlow]

HA!!! Got em............. Got em.

Pipes that arent all bashed up are hard to come by nowadays without spending crazy $$$$

So yea... A brand new pipe with no dents and whatnot made for the low!

 

[ajmps1]

Dude nice man. Make some templates and sell em!

 

[Nottjbarlow]

A very small portion of the already very small community of jetski'ers have access to the tools required to make a pipe nor would even want to.

But I guess if enough people want them I suppose.

 

[jetx]

Good job on the pipe...hope it works as good as it Looks. Looking froward to hearing results

 

[BruceSki]

Guys in the vintage two stroke motorcycle world build chambers all the time.

From rolling comes to hydro forming, there are some cool methods out there. You can't just be a good pipe builder though, you must be a good tuner or you will need stock in Pistons to keep freshening up motors when they melt down.

Pipe looks great though! Let us know how it works out

 

[snowxr]

Now make some outlandish claims about how your pipe make about 40hp more than a power factor. Maybe give it a name, like Firecracker, or Dynamite. A few suckers will think you're the sweet Jesus of pipe tuning and lick your azz all the way to the bank! Lol

 

[ajmps1]

Your certainly not gonna get rich but i bet more people than you think would be all ober it if they met up with an afordable manifold. Fp is so difficult to get a hold of and stainless is easier to work with than aluminium

 

[tntsuperjet]

It's not one of my pipes.
But looking at it. It' appears to be setup for factory B manifold head pipe setup.
Could fit kawi or Yamaha looking at the shape
