    Horse power with headers

    About how much HP. Can I expect from a set of long tube headers with a magnaflow muffler? Motor or rwh.

    I believe that the common quote on here is around a 20 hp gain, with a tune being recommended. You do not list any other modifications so I am not certain if your car is otherwise stock.

    what Jeff said. Great 1st time mod foundation to get your hands dirty. Every other engine mod will benefit from a good set of headers.
