I’m in MA, currently have test pipes (primary cat delete) and cannot pass because of no cats/o2s. Planning to switch to a catless x-pipe but either way you have to swap your factory x-pipe/cats back in every year to pass inspection.

Chances are you'll have to swap it out. Which really isn't so bad

I'm in MA. You need your catalyst monitors to be passed for you to pass obd inspection. The tunes you are thinking of turn off the CEL for the rear o2 sensors for those people that are catless in states that don't require inspection. You will fail with that tune since your catalyst will never go "ready".
You either need stock cats in the car swapped out each year or if you are catless you can try rear o2 spacers and if the cel is off and you check rediness and catalyst is ready then you go get inspection quick. The spacers won't always keep the light off. They just help. |

Oo. Yea the M in stock form is too quiet. You can't hear this great engine. Just leave the xpipe stock then. Buy a rear section. I have one for sale and I'm in MA if you are interested. I also can do install.
