23 hp Kohler exhaust

[wedge]

Hello: Dose anyone Know of a Header or better muffler for a Kohler 23 ?
It's in a Max II .
I have buld racing headers for cars and go karts so I was thinking of trying one out but thought I would see what is out there first ?
Thanks

hi
2 into un 1 is best, primary 1-1 1/4 ,secondary 1 1/2
atv muffler or similar
Remember a ""sports"" exhaust will scavenge more from the cylinders and may cause a lean condition
