I got a set of xenoah pipes but I'm not sure what they are off even tho I believe they are all the same correct? anyways has anyone tried these on a Kohler 440 2as? Or do they just lose power. Obviously I'm looking to gain if I can I'm trying to improve over the crappy single pipe on the sled

But if you are feeling ambitious make a set of the Mod pipes in the HP- bulletin for the fanner.

I suppose I could measure and compare the pipes.

I'm sure there are way better alternatives now a days. I'll see what I can do to scan that for you lemans.

They are all over the place so I'll find a set and take some measurements.

Good topic and great info to know!Just wondering has anybody ever thought of making the outlet larger on a stock muffler? Compared to two pipes coming into the muffler that are what about 1 3/4" dia the outlet is only about 1 1/8" dia.Opening that alone would help a stocker breathe better wouldn't it?

No problem glad to help!
I did make the exit pipe a little bigger. Maybe a half inch and I didn't really notice much of a difference. I've been told to find a merc pipe and get that to fit. But why buy something if you have other parts laying around. If they work that is

Hell yes they work. Will they make your sled fast??? That is all up to you. There is alot more to making a sled fast then just tossing some pipes on it.

If its loud its obviously fast. I'll be doing some other work to it as well. I won't be racing it tho so it doesn't need to be perfect or anything just faster than stock
