I am not ignoring the air scoop comments. I had thought the same and may go that direction when I get that far. I am placing that in the fine tuning stage of the project. I have it where the car can be driven so for now that isn't crucial.
I always knew the exhaust system that came with the engine was not going to fit. I saved the A-1 sidewinder muffler and dual exit tail pipe from the header I had on the type 1 engine and thought I could make it work with some fabrication but know now that the header takes up all the space the the tail pipe would have gone. I still may be able to use the A-1 muffler with a single down turn pipe. Once I have the car drivable I will take it down to my buddy who owns a muffler shop. He is a great guy and has worked on my custom jobs for over 25 years. I can also buy one of the small mufflers A-1 offers to go on the end of the header and use a down turn pipe, I have some room in the wheel well for this.
