Do you have a cat/no cat swap out like FF header does ??

Also is this considered a race header or street?
Will it pass a sniff when getting a smog test?

Also, in general, header designs like those favor N/A applications. I wonder if it will do any good if I plan to go boosted in the future, which tend to favor shorter primaries type headers.
