Default Rockers Arrived!!, Now Best Cat?

What are the best flowing cats out there? I've been hearing a lot lately I don't need a mufflar because they already flow as good as the can. I could care less about sound. Just want the best flowing exaust w/o headers.

So, the Firebird cat works for our cars as I understand? Anyone have a part number just to make sure?

If only a exaust garage would do that. Its illegal here. The only way to do that would be to do it myself. I don't have a welder and am not exaust efficient.

Which is exactly why I have a cat in all of my cars...

If you're looking for a high flow cat, I'd say go with a magnaflow.

Measure your exhaust. Some came with 2.25", even L67'* if you can believe that. Any universal Magnaflow cat.

Hollow out your cat. To the inspection places it appears to be there, and usually no one ever actually tests the emissions. The extent in PA is just your gas cap, and a visible cat.
