If you mean the 4" pipe ... I'll let ya know in ten years 
I wouldn't use less than 12". You got some neighbors you're mad at? Take that at 6am sucker! I'd break it in about an hour then do what ya like on the pipe deal.
Actually I'd do it like I do SB Chevy's. Fire it up and idle it no less than wide open (3000rpm for Chevy) for 30 minutes and call it broke in. I've never lost an engine yet an I use to build some mean SB's. I've only rebuilt 1 K301.

It probably does to ... naw I aint goin there!
So you've got about a 1" hole feeding a 4" hole. Seems kinda like not having a pipe doesn't it.
Just use the muffler for the break in period, whatever that may be. I know Kohler recomends a length of time but I don't know what it is. After that put your stack on and stick your fingers in your ears! It would be better though with back pressure. ALL engines need some back pressure. Because it's loud doesn't mean it's fast or powerful. (I just wish the dirt bike guys around here relized that)

DARREN - Ken & I don't agree on too many things but He's 100% correct about cold air being able to hit Your glowing hot exhaust valve when You shut Your freshly rebuilt Kohler off and warp it all to heck. I hope You have something supporting all that pipe besides the exhaust port of the block....There's not that much iron holding the port to the block anyhow...
Far as engine break-in I'd run the engine on non-detergent oil for an hour, put another change of non-detergent oil in and run for two hours...put detergent oil or synthetic or whatever and run for five hours and Your done! And pull the engine rather hard....don't lug the engine down but keep the RPM's up and make it work. That's what My Kohler service manual says. I personally don't believe in using non-detergent oil for anything besides sharpening My pocket knife but I have NDO in the K321 I hopefully can start this weekend or next.

Darren, I came out of my exhaust port (1" black pipe) with a street elbow, then a 12" piece out past the hood. Then, a 90*, an 18" piece, a muffler with a 90* at the top. Not to heavy, looks and sounds good.
