I did but once I had the car tuned with a KTuner you can shut down the 02 sensor that monitors that cat and you won't throw a code. I have no CEL and pass inspection with no issues.
@Drozey I did it myself but my car probably had really low miles when I did it so the bolts came off fairly easy. I've hear many horror stories of guys snapping studs on the turbo. Use alot of PB blaster, some heat and take your time. As for a Tune voiding your warranty. Yes and no. If the motor pops after a tune then more then likely Honda won't warranty the motor. You could remove the tune before bringing it in but they still may be able to find out you tuned it. Remember Honda has to prove the tune is what broke the car. Regardless it's a headache that you don't want to deal with. Have the car tuned remotely or in person by a reputable tuner. Derrick Robinson from IMW in Carlise PA tuned my Accord years ago and I've had Zero issues. He's the go to for K series tunes.
Did you throw codes with the catless Downpipe?

@@silverspec was it hard or expensive to install and does a tune void your warranty?
