Bullets replacing cats, O2 sim question I'm going to be welding 12" bullet mufflers in the place of my MAC cats later this week. My car will be getting dyno tuned on Saturday, so I can have the rear O2's deleted then. My questiong is, can I drive the car a few miles with the rear O2's on with the bullets and not the cats? Will I throw any codes that will effect the car's performance? Thanks

Re: Bullets replacing cats, O2 sim question it'll set an SES light cause it'll see the cats (lack thereof) aren't doing their job properly... but shouldn't cause any performance loss or damage
