A copla guys here have found that knock counts with new headers were due to the header pipes hitting the frame on hard acceleration. You might try chcking for any points of very close fitment.

I don't think he means to pad the sensor, but more to pad the points of contact with the header or y-pipe.

on the passanger side one of the header tubes is hitting the frame the only way to fix that would be to bend it or cut it i don't want to bend the tube.

Maybe you could put some sort of heat shielding material around the pipe there as a cushion, like header wrap.

yeh i was thinking of that, but i think in time it will rub though. the part of the frame has a point thats the part that will rub though.

Re: esc / ecm (6spd)

When I had header to frame contact with the IROC I worked the pry bar as the mechanic thightened the header bolts.

You might grind off that point a little and then put a hard wood shim (maybe 1/8"-1/4" thick) between the header tube and the frame before tightening the header bolts. Then remove the piece of wood and see if there is then a gap. This is a way to "gently" deform the header tube slightly.
