Ed did a beautiful job of building this exhaust system but it was compromised by the impossibility of snaking the 3 inch o.d. exhaust pipe past the motor mount tubes. Originally we wanted to take it straight down but angled toward the firewall. We finally settled on running it out the side but after it was finished it was clear that it would probably not work because the exhaust ports could see the pipe opening. The exhaust gases would have had a straight through shot. So I chopped off the 3 inch pipe and changed the exhaust pipe to a narrower rectangular (1.75 x 4) shape that I could route through past the engine mount. I have now built three of these and each one has been different due the different configurations of the engine mounts. I much prefer the tailpipes be angled back as in the Mustang 2 but in my own case a vertical pipe is the only way to get past the engine mount. The lower portion of the pipe could still be angled back and I may do that eventually. Jerry

This is a picture that I took at the rotary round up in October. I can't
remember who is responsible for building it.
