Brief Description:	Attach heat muff + fit exhaust pipes
Heat Muff: - Bought a package of 2 screen door springs at Home Depot. - Wrapped them around the exhaust pipe and hooked their ends to the adjacent coils. - The coils wanted to unwind, so I wired the far ends together with stainless wire. - Put the heat muff box around the springs and exhaust, and riveted the box closed. - I still need to put on the stainless hose clamps to hold it on, but I won't do that until I locate the exact position of the muff, which will be after I locate the EGT probes. Exhaust Pipes: - The ends of the primary exahust pipes are too long for the second pipes, so I measured where to cut so the secondary pipes would not touch the engine mount before turning downward. - Cut the ends of the primary exhaust pipes with a hacksaw. Went through like butter, no problem. - Had to use a pipe expander to slightly enlarge the expanded ends of the secondary pipes. Sonex said it was normal for them to be slightly undersized, but it cost me $20 to buy a cheap pipe expander. It broke the second time I used it, but it worked well enough to get the job done before it did.
