I had a washer mod done for my z last month and it was great but now I noticed that the muffler shop I went to set up the gaskets to be spaced out and creates a ringing noise everytime I push the pedal... So I jacked up the car in the garage and got to unbolting the muffler and removing the gaskets completely and put 'em aside cause there's no use for them really. It was a real pain cause the thread of the bolt was destroyed
Fixed now and won't bother me again
