iNVAR Posted June 9, 2011 Share Posted June 9, 2011 Are you SUUUUUUURE there's no leak anywhere? When mine got louder, it was a leak between the DP and mid/Y-pipe. Things don't just get louder for no reason. There has to be a leak. Link to comment Share on other sites More sharing options...
dwolson2 Posted June 9, 2011 Share Posted June 9, 2011 how old is the system? There is a possibility that the inside of your muffler deteriated. Although more likely the exhaust leak afore mentioned. You may have hit a bump and caused it to come loose(piping) Link to comment Share on other sites More sharing options...
LGT For ME Posted June 10, 2011 Share Posted June 10, 2011 Did you check your rear O2 sensor to see if it popped out. When I had my OEM DP on I was driving and it popped out and it went from quiet to holly crap what happened and it was loud. The whole bolt, thread and all popped out so I had to get it welded back on, easy fix Link to comment Share on other sites More sharing options...
