I have a prochamber right now, SES light is on and its kinda backfiring a bit when cold... going to get a tune to clear this up. Id like to try other o/r pipes in the future though, so when switching from one o/r pipe to another, will there still be SES light problems or not since it's already catless?

When you go get a tune the tuner can eliminate the rear O2 sensors or just get some MIL eliminators. SES light is on only because it is registering a fault with the CATS. It will not matter when you go from an o/r pipe to anther. Trust me been down that road many of times.

MIL

With an offroad x-pipe if you get MILs does that recalibrate the O2 signal or does it just bypass it? I was thinking about buying new O2 sensors but if they are just bypassed then that is money down the drain.

Ive already gotten mil's twice, worked for like a week and it just comes back. Put it on the computer and there's nothing wrong with it so i'm just gonna have to get the tune, it does backfire when cold so i'm guessing some air/fuel ratio is out of whack or something.

Exhaust leaks can also cause backfires. You might wanna check that out.
