Test pipe

So just installed my test pipe for my evo x, then the service light turned on, is this natural because i took off the catalytic converter?
The code is P0420
How can I get rid of the service light?
Need help!!

Man you can't just install a test pipe and think everything is ok after you turn off the light. You need to have your car tuned asap.

What brand test pipe? I have the ETS test pipe and never got a light because of the way they have you connect 02 sensor. And get a tune asap. It's pretty critical on the X
