I have 2 sets of the GP800 twin pipes from Factory Pipe. Both sets where in my ski's and running. Putting them all back to stock.

1st set: complete comes with every thing. Pipes, couplers, springs, flanges, lord mounts, instructions, Over all condition is very good. I added a hose over the joining pipe as that hits the hull and will damage it. Was run in a 98 gp800 big bore $ 550.

2nd set: Has everything but needs new rubber couplers, lord mounts and the special bolts. These also had a new plate welded on the front pipe where it mounts to the front of the motor and i have also done the same mod to the joining pipe. Condition is good. This set was run in a 2000 wave blaster 800. $ 400.

Gas valves: full set that is tuned to go with these pipes. Some rubbing marks where the pipes touch. Adapters, covers springs and all.
$ 200

Set of dual 46mm carbs with racers edge mod, intake by ada and riva flame arrestor set.
$ 350.

I have pictures of everything so email with question or what ever.

Thanks

Pat

Pat, Mike,

Is it possible to run the twin pipes on regular 87 octane gas? or do i need 91?

Living where regular is equivalent to $2.42US/gallon and premium is $2.72US/gallon

Sean,
Go for the 1st set. I've seen the pipes through pictures and they look good. Once again you will need to do something about the CDI. I will have a used Pro-tec modified CDI coming up for sale in a week or two. That will work great with the pipes. You'll also need to re-jet the carbs. The price that Patrick is selling either set of pipes for is a steal.

Yes pipes are still aval.
you can run without the cdi but it will not give you all the juice that they offer. i did it for about a month.

take mikes cdi or send it out to be done by pro tec.

email me direct if you want pictures.
