And there you have it! Cheaper than when I bought mine from Emico several years ago, too!

I might add, if you do a search by car type and model year etc on the ARB site there are a bunch of different universal models from different manufacturers that come up under 1977. Most of those don't even fit in the area of the car alloted for the exhaust. That said, those don't come up under 1976 either so I suspect there is some kind of a flaw in the ARB process for a 1976 VW bus. They may be missing something in their records on it - keep in mind that there are actually 2 different 1976 VW bus emission systems. One is based on the 1975 model year system that is exempt and the other on the 1977 and later system. You may need to get a referee to put a sticker on it that says treat this bus as a 1977. The EO is for a truck and that is the main thing. The bus is treated as a truck and not a car. That is what brought this all about - ARB would not allow us to use the car catalytic converters except on a one by one visit to the referee. Some people were allowed to use car catalytic converters, and some were not.

Tom - that is likely a clerical error but I can't speak for BAR or ARB. You would have to ask a smog guy how he would interpret it. I'd print the PDF and ask your smog guy what he would do. I suspect worst case is you could say you have a 1977 engine in your bus.

Nice!

I am grateful for the effort you put in to make this work Steve.

Robbie - I need one please!

came in today. Looks good. I'll test first chance I get and take some photos. Just from eyeballing it, it should fit as well or better than when we tested- and it looks like the catalyst cross section is larger so that should reduce back pressure, lower temps and make more power. Might have a more mellow sound too I am hoping.

Pretty exciting stuff! Just hope they don’t screw something in the process from drawings to production. Kinda like KlokkerKrap...

Almost 3 years but it is done. Magnaflow contacted me this morning to let me know the part is now active and in production. I'll post the new corrected part number later today along with a photo of one mounted on my bus as soon as they send me the sample to test. Since Lyle and I already fitted these there should be no reason they would not fit.

The only caveat I can tell some of you who want one, better start looking for the factory exhaust clamp as they can be harder to locate these days.

edit: new part number is 3391449. It isn't in any of the online catalogs yet but maybe someone like BusDepot Bus Depot will be able to order it and have one shipped. I don't have a price but it is ARB certified as a direct fit for both Vanagon and Transporter air cooled stock exhausts that take a Federal one flange catalytic converter. Should perform better than many others too.

Here is the current late 2017 CARB II executive order showing that Transporters and air cooled vanagons are covered, and this is one can be legally sold and installed in California.

EO is D-193-132. It's all live on the ARB site. Doesn't look like a typo to me.

Let's hope It's a typo or an oversight. Pray

Well it looks like good news for some. Magnaflow's site shows that part number 339449 has now changed to 3391449 here: https://www.magnaflow.com/products?partNumber=3391449&searchterm=3391449

But it only shows compatibility with 1977-1979 'Transporters'. Nothing for '75 or '76

ARB shows these as approved for 1977-1979 too: https://ssl.arb.ca.gov/AftermarketParts/catalysts

A royal PITA that they didn't bother certifying it for '75 and '76 too when it's exactly the same part. Crying or Very sad

Did the bus or vanagon ever come with a three-way cat? And is that what Magnaflow is working with? Excuse my limited knowledge on the subject; just trying to fill some holes in my brain.

Robbie, all CA-spec busses and Vanagons from '79-'83 and all water-cooled Vanagons had 3-way cats and oxygen sensors and the "lambda" closed-loop feedback system to work with them. O2 sensors and 3-way cats are complementary technologies. Wikipedia has a fairly good article on the subject.

All of the available aftermarket cats for our vehicles are 3-way cats. If you inquire about a 2-way cat with one of the manufacturers, you'll get a rather huffy response that "2-way cats are only for diesel engines", which may be true for modern cars, but wasn't the case back in the mid-70's. It's like they've completely forgotten about the history of automotive catalytic converters.

Which brings to light something that I find a bit confusing. In other forums concerning more modern cars that I've read, there is considerable consternation about missing, failed or failing O2 sensors causing a cat to self-destruct or melt down within "seconds" due to an over-rich mixture. Yet here we have several members (Steve, Richard Atwell, and now BusjeCA) who have successfully bolted on a 3-way cat to their non-Lambda-equipped busses, tuned their AFR to 14.7, and obtained enviably low emissions numbers. Not just once with a fresh cat, but in the case of Steve and ratwell, repeatedly. So maybe modern 3-way cats are a lot more resilient than is commonly believed.

I'm also pleasantly surprised by BusjeCA's success with the RMW setup. Last spring when I was going through the exercise of getting my van smogged, I contacted RMW about the viability of using a CARB-compliant cat with their system, and was told unequivocally that the CARB-compliant cats were too large to fit in the space available. I wasn't about to drop $600 just to try and prove them wrong, so I went with a homebrew solution. Kudos to BusjeCA for taking that leap of faith and figuring out how to make it work. Nice to know that is an option when my crossover pipe finally rusts away to uselessness.

BusjeCA, how tight were the clearances for the 339004? I note that you're in Berkeley. Any chance we could meet up sometime somewhere in the East Bay to compare notes? I'm in little 'ol Livermore.


I’m happy to report that BusjeCA passed smog once again with the setup described. The NOX was a bit high but I had it running too lean it turned out. It would have been better with the AFR a bit lower. Nevertheless, it looks like the magnaflow/RMW setup is good for a long time.

Thank you for staying on top of this over the past few years. It would be great to finally see this come to market.

nice to know. He never answers my inquires as to status. I have maybe $1500 of my own money trying to help them help the VW community. Maybe he is too busy enjoying the new house.
