I'm looking at getting a dyno port racing pipe for my 97 670 but it is on a 96 583. I assume that it will work, but I'm not sure. Anyone know? And what kind of specs as far as improvements can I expect? Thanks

They should fit, Just different bore/stroke on the 670.

Thanks SEG, Does anyone know if these are good pipes to use, and what kind of weight and power increase I can expect??

hey SEG, would the pipes be tuned any differently since they were designed for a 583cc motor, or is it all the same? I would look for something designed specifically for my application before I put out any cash.

Did you get that fuel issue resolved?

Good point BRP. It may not be tuned for your sled.

Thanks for the web address RJ, but it didn't have much useful info for me. AAAA for the effort though!!! As for the fuel prob., BRP I haven't got around to checking it yet. I know the fuel valve was open, so I'll pull the line tomarrow and check for pulsing fuel. Denver was playing tonight so I just didn't get around to much! Sorry Pat fans

I'll keep you guys posted. Thanks again.

call your dealer and ask them if they list the same pipe part # for the 2 machines, if no I wouldn't do it.

is this pipe on ebay by any chance?

Jab018 · 09-25-2006, 12:38 PM

Yes, it is, Kid 102.

You can call them and ask, they are very helpful and are located only 30 miles from me.

You def wanna make sure that the same pipe is TUNED for both sleds. You should see a 2-4 hp gain, and some additional weight loss. But when you change one side of the system you gotta tune the other. (You will have to play with your carbs a little so your not too lean)

Those pipes are gone now, but thanks everyone for your thoughts. I'm still planning on getting a set before the snow starts to fly, so I'll make sure to keep this info. in mind.

I have found it hard to beat a stock doo pipe.
