Who Has ported Stock 00-02' Exhaust Manifolds?
#21
There was a back to back dyno comparison done on this a few years ago and the ported manifolds didn't make any more power. If you live in Cali, use smog-legal shorties or just don't waste your time/money.
There's a lot more involved in making power with headers than just bigger tubes.

Side note: The BBK 1 3/4's actually look ok, but of course don't come with a CARB number and won't ever have one! With the increasing smog laws, you'd think there would be money to be made if the aftermarket would come out with a quality shorty that comes WITH a CARB number.
