Sup guys, so today I went and took off the mid pipe catalytic converter. I have a 2012 wrx hatch. I know there's one directly behind the turbo and one on the mid pipe. I only took off the mid pipe one. I also have a custom axel back exhaust (magnaflow muffler with custom tips). My question is, with the cat delete should I be running stage 2? I've seen some nice performance gains with the cat delete. Turbo spools way faster and I'm hitting higher boos levels +.5-1.0 I'm currently running the torqued performance stage 1 map with a target boost of 18psi. Car sounds like a beast. Not way loud but a super deep rumble.
