I am at the point assembling my Pulse 125 where I need to modify the cowl for installation. I have successfully cut the cowl where it will fit over the DLE 20 and the muffler. However, when I have the muffler installed, I am unable to get the modified cowl over the pipes. (See pic) I think I have two options..... 1. Cut the cowl deeper on the muffler side to allow for muffler installation after I have the cowl in place on the plane. or.... 2. Cut a slice through the lower back part of the cowl to allow me to pull the two flaps open as it slides around the pipes. Once in place, I will then screw the two flaps in place on the lower part of the firewall to hold them.
I am not sure which method is the best and am looking for input from others that have faced this decision. If I use option 1, it will make the opening for the engine much larger than it is now, while option 2 will mean the strength of the single piece of fiberglass will be lost on the cowl back. I have attached some pics to help.
