Necroing an old ass thread like this to say "hope to stay long" Is pretty much grounds for permaban here... Nice knowing you.

I was catless and had flames enough to blacken up my bumper and melt parts of it.

This was just the thread I was searching for :laugh:

For local regulations and the once a year check-up, I'm planning to mount a high flow turbo cat. I just want to weld it, because there is no bolt-on solution for mine b6 nbb.

Because my downpipe is now build of 2.5" mild steel, I have searched for 2.5" models.
This one I've found:
OBX 2.5" high flow turbo cat

Because I live in europe, I have the need to order at a webstore (or ebay) that wants to ship to europe.

Does anyone have thoughts about an OBX cat? Or does anyone has a webstore for a better price/quality cat that can be shipped to europe.

If you want to try out cheapo no name metal cat, try this one.
Thunderbolt High Flow Metalic Catalytic Converter 3":eBay Motors (item 370204926354 end time Oct-18-09 12:39:36 PDT)

I bought a 3 inch one for my friends car and it hasnt destroyed itself yet.

martijn 09-22-2009 02:31 PM

It's a shame, they don't ship to europe :(

I'm prob going for the OBX cat. thanks for the reply's

LOL you gripe about $200 for a cat converter? I spent $400 for a 2.5 Magna Flow metal core cat that is CARB compliant. My cat converter is also for a 5.0 Mustang, I am really hoping that the smog guy sees the EO number and doesn't check it to the system.

El oh el, California sucks.
Although, in other news, I have a test pipe with stock flanges on it. I bolt the stock cat back in for emissions testing time (which isnt for a long time, yay arizona)

the ignorant pick on california. anywhere that has obdii testing is exactly the same. I have MORE inspections to do here in Virginia than I ever did in CA.

And people laugh now, but almost every state is eventually going to adopt cali's ways, if not every state. Washington I is next :(

CA has this new policy though. You must use an OEM or OEM approved cat converter that has an Executive Order number stamped on it. So far Magna Flow is the only game making after market CA cat converters :( and yes, soon the rest of the US will follow :(

Here is the part that will just send you into flames. Magna Flow stated that the CA approved cat IS the exact same as there other cat converters. The difference is that it has a EO number stamped on it. BUT a CA cat is $300 MORE than a regular cat, because they had to spend the money to pass it by CARB :vash:

I have the one from Enthuza. I decided to keep it at the last minute so I don't have to jack with it when the guy who does my inspections goes to prison.

ODB1 FTW, and what about everything having to be carb approved?
