i just had a downpipe and decat fitted to my standard cat back from a garage, iv only drove it a few miles back to work and when i put my food down there was a viberation from the dash. it was a 3'' downpipe and decat gitted to a a3 quattro, what could it be rubbing on? is there any danger in it? im at work now and cant get under it to look at it until the weekend?
