Default Bolt on with headers

ok so i am looking at getting supermaxx headers and so i did a search on how much headers add to minor bolt on cars. my car has to be emissions legal in texas so thats why i need the supermaxx with cats. anyway what i am looking for is dyno and/or track #'s (not opinions) of actual people who did before and after with headers only on bolt on cars (no cam or spray or anything else). i found a few posts on what i was looking for but not enough. what a i found in the search was anywhere from 19-27hp and 15-23tq. thanks for you help.

I went from 314rwhp 333rwtq to 343rwhp 359rwtq with the only changes being a set of hooker long tubes, offroad Y pipe, and B&B triflow exhaust. I have a dynograph of the after numbers if you'd like to see them.. can't find the graph of the befores.

Why do you need to stay emissions legal? PM me if you need an inspection.
