mazzuri super headers
From CA DMV site:
This is actually relaxed from previous versions of the smog abatement program. It definitely used to be four years, then 5, now 6. But you still pay a tax for smog abatement regardless of your testing status. Just another reason I left.
Also, the majority of states outside California will allow you to install catalytic converters with the Mazzuri headers and pass their testing as long as the cats are measurably doing what they are intended to do. You will pass a visual because outside of California the visual means presence of the cat, not presence of the OEM system in its original configuration in its entirety.
Vehicles registered in areas subject to the biennial smog certification program are required to submit evidence of a smog certification every other renewal period. Owners of vehicles six or less model years old will pay an annual smog abatement fee for the first six registration years instead of being required to provide a biennial smog certification. The registration renewal notice mailed to you by the department will indicate if a smog certification is required. If a smog certification is required and you have not had a smog inspection, you may still pay your registration fees to avoid any late fees. However, you will not receive your new registration or year sticker until the smog information has been received by DMV.
NOTE: Upon initial registration, nonresident and specially constructed vehicles 1976 and newer require smog certification. The six or less model years old rule does not apply to these vehicles.
When you transfer a vehicle that is four or less model years old a smog certification is not required. A smog transfer fee will be collected from the new owner. When a vehicle is more than four model years old, a seller must provide evidence of a current smog certification except when one of the following occurs:
* The transfer occurs between a spouse, sibling, child, parent, grandparent, or grandchild.
* A biennial smog certification was submitted to DMV within 90 days prior to the vehicle transfer date (a vehicle inspection report may be required for proof of certification).

Beginning April 1, 2005, vehicles being initially registered in California that were previously registered in another state are exempt if the vehicle is a 1975 and older model-year vehicle. Newer vehicles, the first 6 model years, are not exempted upon initial registration in California. These vehicles are required to undergo a Smog Check Inspection.

You're screwed in any state that does a visual emissions inspection (which is a lot of em).... You might can find an exhaust shop to make some generic cats fit the mazzuri headers though and that would get you past visual in most states if the inspection place doesn't know what to look for (which is a lot of them who just check for the right number of cats)
In CA however that still won't work as the headers won't have an EO number, so swapping before inspection would be the only choice.
I don't think CA requires inspection for the first 4 years or something on a new car so you'd be ok for a little while anyway.

Coated headers will result in a cooler engine bay, and hotter exhaust. On turbo applications, the hotter exhaust can lead to improved performance. I doubt there would be much of a difference in performance on our cars.

Thanks, so there is no reason to coat Daniel's headers for our IS's.

My understanding of coating is this... It provides a heat barrier and provides some rust protection. supposedly it helps smooth the airflow and help with the vacuum effect created by well tuned headers and help prevent buildup on the insides of the tubes, so debatably there is a tiny power gain from doing the coating.
The other bling aspect to coating is it will give them a high luster finish so you won't see the joint welds, metal discoloration, etc... Or you can choose to have them coated whatever color you want. This IMO doesn't matter much for our cars being you'll never see the headers.
Average price I've seen locally is ~$200 to have a set done.
