Hello, need some help. Just put a 2.5” straight through on my mk1 fabia and it’s vibrating underneath the car and I haven’t had time to jack it back up to see where was just going to ask if anyone knows if when you put the larger exhaust on was I supposed to replace the rubber hangers with slightly longer ones or is it because I’m slammed and it’s vibrating between the underneath of the car and my rear axle? Thankyou!!

Heat shield is resting on something I reckon.
