euro headers vs us question
So our cars have 333hp, and euro ones have 343hp crank right? Yet people who just switch to euro headers, are gaining 15-20RWHP. Doesn't make sense to me. And why are europeans selling their headers, are they upgrading to something that gives significant gains over stock euro headers?

A few of us had a good deal on SS so swapped to SS stepped headers recently. The car spends most time on track so this was a worth while mod to make. It was the final box to tick as i'd already swapped to 100 cell race cats and an after market back box prior.
Am due to track the car for the first time at the Ring in 2011 this coming w/e so will see if RobMCoupe's assessment holds true - i hope it does... |

IIRC, the Euro cars have a different section 1 with a beefier cat to make up for the lack of cats in the headers.
