Another short tube header topic.. Questions

Hello TW,


I just ordered a pair of short tube headers. Let me tell you, my headers are so rusty and crusted from the constant maine weather it was definitely time to get some new headers.


I understand the complexity of the install. I have a friend who is a welder and a weld inspector so he will be doing the tricky part of the install.


My question is: what are the best cats (for 100-125$) to attach to these headers. Where I live, it's very easy to get a sticker.
