I figured shielding wouldn't be enough. Kind of a bummer because I am not going to do it if I can't get it to pass the BAR.

I sent some manifolds to Vorshlag for test fitting in their E36 and E46 swaps.
The LSA and LS3 manifolds are surprisingly close fits in an E39. See this build thread by zr6sbc titled "540i-LS3-TR6060": http://forums.bimmerforums.com/forum....php?t=1766180
zr6sbc's method of doing the LS3 E39 swap is a viable candidate for a California-legal LSx BMW swap. I intend to get some of those manifolds to test fit in an E36 and E46 and see how close they are.
Im pretty much in the CA registration boat which is why I stuck with OEM manifolds. It was good to read about the possible wiggle room associated with the cat location.
Coincidentally, rao posted a manifold thread on LS1tech. Someone there introduced these Holley manifolds. Maybe they'll get the CARB stamp? Maybe a new candidate to chew on.

540i-LS3-TR6060 swap thread
Non-Ca resident but how does the DMV know if your engine has CARB approved headers?
Bi-annual emissions tests which include visual inspection of the vehicle. For engine swaps, the vehicle has to be taken to a special state-operated BAR referee station where the swap is inspected with a fine-toothed comb. They will look at part numbers on catalytic converters, scan the ECU for the software version, look for modified parts, and make sure everything is installed in the new vehicle as it was in the donor. The special engine swap inspection only occurs once, and then normal inspection stations can test the vehicle. They are less likely to spot something like non-stock manifolds that the BAR referee usually notices.
I know I'm bumping my 2-year-old thread but I have a car now (E46) and I still want to do this swap eventually.
I did send a bunch of manifolds to Vorshlag so they could test fit them on various LS swaps but I haven't heard back from Terry Fair in over a year, so they probably haven't made any progress on it and I haven't had time to bug them.
Anybody try these out?

Any pics of the shaft you built? I am just having such a hard time coming to terms with $1200 headers in a car I paid $1000 for.
