Bolt on exhaust kit

I need to get an exhaust for my 1968 Plymouth valiant equipped with a 225 slant six with a 3 on the tree. I was wondering what brands you guys run or prefer for a bolt on exhaust kit.
I made my own out of 3" stainless and some pre-bent elbows. 6/1 header with a 3" collector. Borla SS mufflers. Obviously you can use mild steel if you want to cut cost a bit, but it rusts, hence why people replace exhaust systems.
