how much clearance can you(or do you) have behind the motor and firewall?

I want to run the slimline pitts muffler on one(planning to cowl it with the fiberglass specialties cowl) and need a clearance estimate. Haven't picked up the plane(still debating whether to kit or not) yet so I need a favor from one of y'all, and I figured the beginners forum might attract a few hits.
Mine has an OS 75AX mounted almost as far forward as one can safely go on the standard supplied mount. With the battery mounted just forward of the servo tray the plane took just over an ounce at the nose to balance. I'm not sure how the weight of the two engines compare but that should give you some idea of how much room you may have.
