Replacement exhaust options for 535i in CA

I'm curious if anyone has any good tips on replacing an exhaust (headers back at least) besides scouring the internet for an OEM someone wants to part with. From what I can find, I either buy the components separately: muffler, cat, pipes, maybe headers and hope they all fit together. Or get a custom set made, and probably still buy a CARB complient cat.

Cat back really doesn't matter in California and several options available.
Headers back? Headers are a no no in CA so I'm going to guess you meant exhaust manifolds back. Options range widely but you're going to have to use a CA compliant cat, or the original. Most smog techs don't really check but if it fails amd they notice no catalytic converter it's a problem.
If the car is stock, and has a catalytic that passes smog, just run a cat back system. Do a search on the forum amd you'll get some information.
