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.
