I have a magnaflow cat on my ‘15 and an hks exhaust. I’ve been wanting to remove that resonator at a trusted shop for more oomf. I just want a stainless pipe from the cat to the axle back. Just so you know. The cat will increase the sound inside behind the fire wall. Sounds great!

Just a heads up. The o2 sensor went bad a few months after the install so be prepared for something similar just in case. Those things are about $100 plus a few bucks for install

I’m not sure to be honest.
