Seems we have some folks who thought the use of header wrap was legal on OEM manifolds as well as aftermarket headers. I can assure you it is not legal. This has been very clear w/ the Director staff as long as I have been racing in CMC (I asked in 2004) that it is not legal. You can use it on any part beyond the manifold itself, but not on the manifolds. If you have it, you need to remove it to be legal for 2012. Platforms allowed to have non-OEM manifolds can use a part that is sold w/ an exhaust coating, but that does not allow the use of a header wrap.
Sorry if you have this. Please do not make me issue a DQ.

I know of two folks at this point (no need to rat yourself out). No need to name names. Lets just get it resolved.
