1 7/8 headers

I have used both. Currently have 1 3/4" and sold the 2" as they were miserable to work with. They fit great once one, but man I hated those things. I think the 1 3/4" could be hurting my combo some so was trying to find something a little bigger. May just have to make a set myself, but not sure if I have the patience for that.
Is it primarily a street car?
