Depends on the pipe your going to use:
Hope this helps;> Bill O Neal said...
Here is something to consider though. From my experences with both pipes, the XPL pipe makes more rpm, by about 100 rpm or more. But, when using the pipes in an SXR, you may not want or need that extra 100 rpm.
One good reason to use a 951 in a standup is to get the more lineal powerband that a 951 offers over a conventional Kawasaki standup engine. You cannot make fast lap times on an uncontrollable standup such as a highly modified SXR motor with it's peaky powerband as compared to the more lineal powerband of the 951 motor. An SXR with a good running and well tuned 951 will go well into the high 60's mph low 70's or better. Just how fast are you capable of going, and turning, an SXR ? Does it really matter which Coffman pipe you use ? How will cutting and rewelding it effect the power and rpm?

I totally agree with that,thats basically the same effect I got when I put the 717 engine in my X2 ,the power delivery is very smooth and linear,anytime you grab the throttle its there regardless of rpm,it makes for a very controlable and rideable ski.

Exile, Im pretty sure that quote from Bill was in reference to the different Coffmans pipes available for the 951, not the difference between the coffmans and factory pipes. They (coffmans) have a GSXL pipe and an XPL pipe. The XPL pipe is known to make higher RPMs, but im pretty sure that the reason for the difference is that the pipes are a difference length.
The thing about it is, that when you put the pipe in the SX-R hull, you need to shorten it anyway, so I think the pipes end-up performing very much the same anyways.
As for the factory pipes, they are twins, and that would be a tough fit. There isnt that much room in the SX-R, but im sure if you really wanted to get it done you could make it happen. Probably wouldnt be worth it performance wise though, because like Bill said, how fast can you handle going anyways?
As for fitting the coffmans in the sx-r, you need to cut, shorten, and rotate (thats how I have seen it done) the stinger end of the pipe (and then weld it back together). You basically cut a couple inches of the pipe completely out, then cut a ring of the outer jacket out so you can weld the inner chamber back together, then you re-weld the ring of the water jacket back in place.
You also might need to shorten it up a little bit near the exhaust manifold, and then I am pretty sure you will need to relocate the mount bracket on the pipe. All in all, its pretty simple and straightforward, and when you have it sitting in front of you, you will see exactly what needs to happen.

Yeh, thats the way I have seen and I am thinking differently as well. The way I saw it, I feel like there is enough room to keep the pipe going straight out the right side of the boat, the way it normally does. I was just going to throw an inline silencer in there. I'm not positive it is going to work, but that is what I am going to try.

I hear that the stock pipe can produce more bottom end than that dry pipe but will thestocker fit, although the stocker is 20lbs. oooucchh!!! I heat they have killer torque. I'm going to run mine out the right side with a water box.

stock pipe wont fit, the headpipe clears better than the Coffmans, but the tail section does not.
Also be careful how much you shorten your Coffman pipe, people are adding length back to them, just to get them to run on the bottom
