 I doubt if the aftermarket headers make 2 HP and if they do, it's at the detriment of the torque band. Unless someone does the dyno comparison they are equally good.

 

Grassroots Motorsports Magazine routinely dyno’s exhaust setups and there is no major percentage improvement over stock headers. Sometimes there is a HP and torque reduction!

 

If you’ve built an all out performance monster, get the Delta headers. If not, you may not notice the difference, after all, you’re not replacing cast iron exhaust crap, you’re replacing a header with a header.
