Fountain Factroy Mufflers
 

My 35 Has The Factory Mufflers, Obviously At Times
I Miss The Loud Rumble Of The Engines. However On
The Other Hand I Can Pull Up To Water Side Resturants And Not Get The Hairy Eyeball Either.
Performance Loss Is Undetectable And You Can
Carry On A Conversation While Running At Nominal
Speeds. Anybody Else Have A Comment?

You want to open your exhaust at anything over 2000 rpms. Run 4000 rpms with silent choice on, then turn it off and feel the lift. Mufflers are only for idling around.
