how much would adding headers that are 6:2:1 give me roughly

[johnj92131]

Simply not enough information to provide a reasonable answer.

 

Assuming a Comanche, What year?  Stock engine? Are headers long tube or short tube?  Tube diameter?  If your ignition iisystem is not in top shape, headers will not help at all.  Because headers tend to do more at the high rpm range.

 

Want a bit more power from a stock Renix truck?  See Cruiser54's renix tips.  One of them is to use a 1990 ecm.  Another deals with an exhaust restriction built in at the factory to speed the engine warm up.

Yup. Get all the basics done.
