Guys has anyone done a dyno test on the 2000+ (or whatever year the change was) stock headers versus aftermarket headers? Two of you have told me that the newer factory header is very good and much better than the older design... and that an aftermarket one may be somewhat of a waste. Then I get a different story from aftermarket tuner companies. Of course they may be just trying to sell something.
I was wondering if there is anyone that has tested this. I want to know if its worth the extra $1600 investment to buy headers for a CTSC 2005 car.
