My shop teacher has a 2 foot long horn with a threaded end that will fit into the exhaust port of my 15hp horrizontal shaft Tecumseh. The flare is about 8 inches across. Massive ear bleeding SPL? My 11 hp briggs is already so loud with a straight pipe, your ears ring after hearing it for about 1 minute.
