any luck passing with a bbk catted h-pipe??? just wondering if i need to find a stock h-pipe? thanks!!!

djay

It should be able to pass if it's CARB legal; is it?

bdog

i think.... its got the bbk stamp on the pipe itself, so i would assume so.

No, you won't pass if they see it. And it probly won't pass the exhaust probe test either. I heard a rumor about a Magnaflow CARB legal mid-pipe coming out soon, but there isn't any aftermarket mid-pipe that is legal for our year mustangs in CA.

bdog

well i guess i need to find a stock one then ....

It sucks, I had to change back to a stok pipe when I moved back to CA.

I hate living here when it comes to anything that has to do with cars...lol

tbirdscwd

Me too. Its a pain, but there are plenty of legal mods, you just have to do a little research.

I was told it doesn't matter what kind of pipe it is, you just need 4 cats because thats how it came from the factory. So you might be able to just weld in 2 more cats.

Not in CA. The midpipe has to be the STOCK pipe. The replacement midpipes don't all have OBDII certified cats. Just having 4 cats MIGHT pass the exhaust test, but it will not pass the visual.
