Recently bought an isr single exit gt after installing i noticed the resonator was very close to the drive shaft but is still cleared. Afer lowering my car i drove it up the street and noticed a vibration so i jacked the car back up and the resonator was rubbing on the drive shaft. Anyone else have this issue?? I checked to make sure everything was installed correctly and it is and i haven’t heard of this issue from other people and reviews of this exhaust
