Is this needed right now my car has no cat I wanted to know when I add the cat will I need the hanger also pics would help, thanks in advance for any help
If you don't run the hanger.....the exhaust system shaking / resonating will cause vibration from all that extra weight not being supported & you may end up with turbo down pipe bolts that are constantly loosening. Who knows what effect fatigue will eventually have on the metal components of your exhaust system.
It's best to support things.....that's how the engineers designed it in the first place.
