The CEL is NOT an issue... Is just the sensor doing it's job.

The function of the sensor behind the primary cat is to monitor the adecuate functionality of the cat converter.
When you remove / delete the cat converter the sensor obviously will sence a cat failure and throw a CEL.

The Nitto midpipe is a catless unit threfore it will trigger the CEL.

When you say you are going for a custom mide pipe are you planning to go catless also? If so you will have a CEL and you will need one of the already mentioned CEL fixes.

If you keep your cat or install a new cat to the custom midpipe you should be alright and will not need any fix.

Just my recomendation:

Keep the cat... the gains for going catless should be minimal on this engine. Just ask your shop to make your midpipe from the cat back...
