Default Headers for Series 1

Anyone here own a set of aftermarket headers for Series one? If so, what did the installation of them do to your torque curve, and HP rating?

Also, can you feel any difference from this upgrade?

Nobody makes them, except custom. I'm not aware of anyone running them, but the factory manifolds are very similar to a header design anyway. With the valve sequence being screwy on the Series 1, I'm not sure there would be that much of a gain.

the best thing to do to our manifolds is to have them weldes on the outside of the tubing at the head flanges and port the welds out of the inside, then have them ceramic coated to reduce your under hood temps.
they claim that for every 10* of under hood temp you drop, you gain aprox 1% HP
