Are these things the regular Carsound cats on Ebay for 35 bux??? If so isn't that kinda a great deal. I keep seeing them around for a lot more than that, but no one says ebay, are they all knockoffs or what? Just curious. Looks like any size up to 2.5 is only 35 on the buy it now feature, then I guess the 3.0 is a bit more???
Like faith said, you MUST have the OBD-II compatible cat. I bought mine for $65 shipped, search and you should find my thread with the details. And you can get any size you want.
