Well kept getting codes for running lean on bank 1. Took the cats off acouple days ago and bank one was hollowed out. Bank 2 was just fine. What do you guys think happened? I guess those BBK catts aren't all that after all!!!. Gotta love the raspy x pipe now with the flowmasters. Sounds like a damn freight train driving down the street. Funny part is I have NO CEL on now. It hasn't came on at all. Which is weird cuz I was going to buy some MILS to fix the problem but it isn't a problem now. Probably going to go with the Magnapacks now.
