So a little while after I put on my mac flowpath catback I noticed there was a pretty bad exhaust leak where one of the chrome pipes attatched to the muffler. Tightened that up and the leak was gone... but now there is a horrible drone from 1500-2000 rpms! I thought this mac system was supposed to be low on the drone, but this is pretty bad considering that I have dynomat covering the entire hatch area. Anyway... how could fixing this leak make such a loud drone and is there anything I can do to minimize it besides loosening up the exhaust?
