Exhaust cutout before the cat

[HappyLemon7]

has anyone done an exhaust cutout before the cat? I know it wouldn’t sound the best, but I’m curious if anyone has had any issues since it should decrease the back pressure significantly.

You will have overboost issues unless you get a tune specifically for zero back pressure. Not worth it in my opinion.

Don't forget the sound, which will be absolutely horrible.
