Buckeroo

I'm looking to replace the exhaust system on my 1937 business coupe, and I've been unable to find anyone who makes one. If someone could point me in the direction of somewhere that makes them, I'd appreciate it.

I've got a 49 olds 88 with the rocket V8. I'm in a constant starting battle with the 6 volt system, and trying to decide what to do. I've read up on 6 / 12 batteries with solenoids built in, and I'm looking for any insight as to whether this is the best choice.
