Received the "bolt in" cats today - but the flange is the same style 2 bolt, 3" flange as what is on the B&B exhaust - not the donut style flange for the stock exhaust.

lasstss - did I get the wrong things?

Probably not.. The donut in the factory cat has to be pulled out and switched over to the RT cat.

Thanks. Sorry. I'm an idiot :cookoo:
Me too, I did the same thing. It looked like part of the OEM pipe. Of course when I went to put them in my cats it fell thru the hole. I had to return the cats as RT screwd up. Hopefully, yours are correct.

ARGHHH...ask me how I know this...go ahead....:thepan:

I drove around for like 4 months without the donuts in, as I knew no better.

On a positive note, the donuts are back in now, and my car doesn't sound like a Chevelle anymore.

If possible, PLEASE post a a before/after RT Cats dyno.
