How do I know if I have the upgraded heat exchanger? Mine is black, measures 24" X 7" X 1". Looks pretty small. I thought the better one was silver colored and much bigger? Anybody know where I can get a better one that will mount up without having to fab my own brackets etc..?

 

From you measurements you have the newer heat exchanger.Maybe someone painted it black?

 

Mine's like 14-15" wide and I have the old style, so it looks like you have the right one.

 

I have the same one, bit it is silver and aluminum. You probably wont be able to get a bigger one without makng brackets. I was looking at Lightning/Cobra heat exchangers. They run between the 300-450 price range and very large.
