How much is good air worth?

Thanks guys for your comments.

No Ed ... open headers are illegal. We can run the OEM exhaust manifolds open with no mufflers but if you run headers you must run mufflers. We run 1 & 7/8" American Racing Headers, an off-road X-pipe with no cats, and GM C5 Z06 titanium cat-back mufflers.

As far as the MAF I believe that has to be present as well. When you guys talk about open and closed loop, etc. I'm not sure what you're talking about. We get our tunes from Stephen Covington in Longview, Texas at East Texas Muscle Cars. He seems very knowledgable and takes him time tuning the car on the dyno and on the street when we go. The times and consistency that the car runs have been pleasing to us.

So just buy two new ones and replace them?
