another exhaust question
i bet everyone hears this all the time but im thinking about getting bbk equal length shorty headers with a bbk x-pipe with cats. i have a dynomax cat back system right now. so the question is will this still pass emissions? thanks for the help.

That depends on other things. Is your smog pump hooked up?
Are your O2 sensors good? What other mods do you have? The more mods you have, the more emissions your engine is going to produce. I'm not saying a modded engine won't pass emissions but an engine that is stock or very close to stock will have a much easier time passing smog tests.

No problem, reason for getting it hot is so that the cats are at operating temp, and burn off the unused fuel well.
