Anybody have any experience positive or negative with removing the stock Cats or replacing with Hi-Flows? I'm doing some exhaust work on Monday that I haven't seen anyone do yet so I hope I'm the first. Don't worry I will post pics after!! But I tried to contact MadTuner to get his thoughts about the cats & if he can trick the O2's so I don't have a check engine light but he hasn't returned the call yet.
