I have a locked 2021 supra and I really want a new downpipe. I thought about getting the AA downpipe, but $1400 ouch. so I was wondering if I got a different downpipe that set my CEL off could I clear the code using JB4? if not what can I use?

I have a locked ecu 2021 supra 3.0 and I want to do some mods. I ordered an Arma speed carbon fiber intake. I would like to do JB4 tuning, but I'm afraid that I will void my warranty on my brand new car. Do you guys have any experience?
