Invidia Midpipe ('14 3IS)
Is installing a catless Invidia Midpipe a bad idea when it comes to check engine lights and thrown o2 sensors? I hear that the cats in the midpipe are secondary, knowing this, are the secondary cats monitored by o2 sensors? I guess the question im trying to ask is will i get any lights on if i change the midpipe, and will the service guys at the dealership get all worked up about 2 missing cats?
