Title: Exhaust size
Post by: Connor32 on March 27, 2017, 05:43:56 PM
I have a Jed 111 with the 12 hp and was wondering when I remove the muffler what size should I make the straight pipe, also does anyone make a performance air filter for it.

if its a K301 Kohler use a 1 3/8 i.d. pipe 24-28 inches long.
You can get a K&N from Stens that fits in the stock air cleaner
housing or get an adapter from Zach Kerber or Vogel mfg. and use
the 2 7/16 hose clamp style one. May be other options as well but these
are the ones I know of.
