I do have headers . 2 1/2 mandrel bent with X pipe. Dyno max Ultra flow. In my opinion a decent flowing exhaust. Reading the post, not sure if I have made up my mind yet to try cut out yet. BUT if I do ,will do it on the cheap . A set of "header reducers" welded into place , and make a cap. Cost about $40 . I would have to unbolt them by hand , but like I said just want them for the track so who cares.
