Only shorties. Not long tubes. Even long tube headers that have the AIR tubes for the AIR pump do not have a C.A.R.B. number.
Hooker makes CARB cerf headers?

shorties are your only legal option here... if it matters, LPE uses shorties on their builds.
They do help. There is an improvement in flow, but not as much as say LTs. the biggest advantage is weight savings.

CA's website has a page showing all the EO numbers if you dig around for it.

If you unbolted my exhaust system and put it on an 86 (with the same motor btw), then it would suddenly fail the smog visual.

My last inspection, the tech didn't even pop the hood until after the test, and that was just to b.s. about the TPI since he had a firebird at home. For the visual part of the test, he just pressed the "OK" button over and over again.
