How many HP the combination of STILLEN exhaust and Xerd headers will brings for G coupe?

 

May be a streach, but I believe that those headers dyno'd 17hp, add the 8hp on the Stillen exhaust from the dyno shoot out and you have 25hp.

(one could research the header on my350Z.com)

I have already done the stillen exhaust and thinking the xerd headers. I think,sometimes,that this cannot be figured out by the way that put HP gained together for final gaining we will get. Sometime it will be greater than we thought but also sometime they are negligible. Finally,first,they are really good combo in my mind. Waiting for the result.
