Can I pass inspection with long tube headers?
I would like them but I don't want to put them on then find out I can't legaly drive my car any more.
What are your experiences with inspection stations.
Thanks.

it all depends on the laws of your state.
here in illinois, they dont look under the car so if you have headers, make sure they get tuned so you pass emissions.2000 nhra edition formula

I live in N.C. I heard most places don't look for the cats although they are supposed to. Will there be any different readings from the exhaust when they try to read it. Or hell, do they even read exhaust measurements in NC.

Ive got long tube Pace setter headers and 3 inch to the hooker muffler, SLP air box, Cam and torque convertor changed and Jeff did my dyno tuning. He is a great person to deal with. My T/A runs 11.80s flat at 115 mph in the 1/4 & 7.50s in the 1/8. If you do what I did plan on changing the carrier in the rear end, (weak with good tires, mine broke).

could you put the CATs on the end of the LTs or is that just dumb? How about midlengths?

Yes, LTH's will make more power w/ cats than MLH's w/ cats.
LTH's & MLD's are not as efficient at eliminating emissions as factory designed systems are. When you cold start an engine, it takes a while for the cat to heat up. When the cat is cold, it does not do its job of eliminating harmfull emissions. The shorter the distance from the exhaust manifold to the cat, the less heat escapes which is less efficient. This is one of the biggest reasons that midlength and LT headers are illegal. They do not get to the operating temp.'s that carb legal parts do.

How do all of you guys manage to have headers on your car? Do you just take the risk?

I live in PA and they ODB and visual test, but most shops don't really care about visual... Also, in PA if you drive under 5,000 miles/ year or spend $150 on parts and labor to get (emissions) stuff "fixed" you get an excemption. Call your DMV and see hwat they say about the laws, and then ask around to find a shop that might be willing to look the other way. I'm getting headers soon, and I'm kinda hoping I don't get caught with a visual... Good luck!
