Calspeed headers on 4x4 anyone done
 

I've been looking. What does not clear on the headers on the 4x4 trucks ??

the driver side hits the front diff mount the passenger side it's the frame barely. also the o2 sensor needs to be re clocked so it won't contact frame rail

I have calspeed headers.. We just messaged the primary a little on the driver side. Pass side is close to the frame but doesn't touch.

Awesome guys thanks that's why I thought that the diff mount might get in the way a bit .

We had to massage the primaries at the driveshaft as well as the steering column on my buddies silvy SS.

and when I say massage I mean beat the piss out of them with a hammer/sledge.
