Default Fuselage and engine cowl

I have found many useful tips in Tips & Techniques about how to cut an engine cowl but I find myself in trouble here.
The fact is that I have to assemble an IMPULSE (www.bnmodels.com) and in this ARF the fuselage and the engine cowl are one single piece of fiber glass, so that it's not possible to remove one from the other.
The engine can be mounted through a large opening, however I need to cut the cowl to let the muffler protrude off one side.
The plane deserves a neat job here and I really wonder how I will make it.

start with a reference point such as center line on the engine mount. then measure measure and before you cut anything measure again. avoid at all cost the "ive cut this 3 times and it still too short syndrome".
have fun

You are right, I need to start from somewhere in a logic way.
Thanks

I am thinking to build an engine cowl template. All I have to do is to bolt the engine mount, and then the engine with muffler, to a dummy firewall and take measurements for determining where I have to cut the cowl.
The most difficult part will be transferring the mesurements to the real cowl in the most accurate way but I believe it would be possible.
