Where is your 2nd head pipe?

As far as I remember, a single pipe gives more torque, twins increase peak hp
Everything has been tried in the past when there was a lot more money flowing into the sport. The 1995 WF winner had custom twin pipes in his 750sx. The current freestyle boats can barely house a single pipe, and most importantly, riders aren't asking for twin pipes. For a freeride standup, I would rather not have a pipe at all since the power surge makes it more difficult to control. Racing has gone foutstroke so theres little demand for the ultimate tuned pipe.

You can run dual fmf pipes too! Guy that posted the photo's says the ski runs well like this.
This is kinda what I was looking for, just some history behind it and if anybody had tried it before. I rely on you guys for this history, I was only 1 in 1995. Lots of cool responses here.
Both head pipes would need to be smaller diameter than current b pipe. Rear cylinder head pipe would be similar to the current setup, but there is a few inches room to be further towards the tray. Front cylinder head pipe would be a similar shape and run alongside, but in front of the rear headpipe. Front cylinder chamber would be the upper one, distanced the same from the piston as the rear, so slightly more towards the nose of the ski. I’ve obviously never put anything together and it’s more complicated than I’m making it seem.. but it’s just the idea I had in mind.

I don’t see the problem, Seadoo did it from the factory.
which seadoo had factory installed twins?I don’t see the problem, Seadoo did it from the factory.

Factory PIpe supplied the pipes. No Warranty......
I have been there and done that. I know what your thinking and I couldn't be convinced by anyone that twins on a stand up were not ideal. I had just had to build my own. I did this about the same time the TBM's came out - winter 04'. Mine were made using some stampings that were made for the GP1200R for Rius. I also made mine dry...waterjacketed. (More work, more welding, more time, and more weight!) Lots of time, did I type lots of time? tons of time. Looking back it was something I'm glad I did. Just like painting a car...did it once, never again. The twins worked....I broke lots of parts from vibrations. I also owned at least 3 sets of TBM's. TBM's fit better and worked good. However it was hard to beat the overall performance of the FPP single pipe. Twins definitely spun higher and carried the ski to higher speeds. I tried twins with stock, limited, and stroke mod setups. All cases nothing produced the top speed of the twins...... but no twin setup matched the snap of the single pipe for racing around bouys
Twins weighed 45-47lbs dry. Mine and TBM's

Yes, pretty cool ski. From the factory with factory pipes and a Skat Magnum pump among other goodies. They only made 500 and you had to have an IJSBA card to purchase one and as Kahuna said no warranty. 951cc with 160HP and the engine had a very short life span, I think it was something like 25-50 hours on rebuild intervals. It was a race ski.

They had twin pipes in a X-2 back in the day. I believe they were made from js300 and 300sx Kerker pipes.
