cattman is a phone call, most stuff is make to order, and he waits until he has x amount of orders before building them. In short, it's a wait, but well worth it.
OBX makes them, but I'll let others chime in with reviews and brands other than cattman, because I have no experience with them personally

 

So I'm going to get Cattman Headers, Is this a job I should try tackling myself? (First major D.I.Y. mod id be trying) I'd appreciate it if someone had a more picture detailed writeup for Cattman. Besides soaking all bolts,any tips? Is removing the rear really that difficult?
