OBX headers

Has anyone used these?

Also, are these specs ok for LTs?

I wouldn't use primary tubes that small, but the smaller diameter tubes are suppose to be good for low end torque, compared to the large diameters.

I think I am debating between these and the PaceSetters with their offroad Y pipe. I like these because it is a kit with some resonators but I read to replace their hardware and get the locking bolts.

Also, May go with a comp 260 cam. So would the bigger primaries be the best bet with that?

The Pacesetter's with the ORY works great for me. As for camshafts there always seem to be a better camshaft down the road. Or so I've often been told....

Yeah I will wait and get opinions when the time comes haha. For now, I will plan for the future as much as I can while getting headers lol. I wish we could get the built trans situation going. I would just get my ProCharger and be ok with that!

Get on that ProCharger! If there's no trans available stick a 46RH/A518 in it....

Try and find at least 1.75" tube prefer 1 7/8"

1.5" is to small.

I remember looking at these a few years back and I don't think those are actually cats, you have to pay more for the model that has cats. May not be an issue for you but you will need a custom tune to get rid of the check engine light.

Somewhere way back in these exhaust threads there was a mention that the OBX system was the same as the Dynatech but was ceramic coated as well and came in for about $600.00 less than the Dynatech...I know the Dynatech is good but don't know if the thread was correct. If it was then the OBX is definitely a better deal IMO.
