Exhaust Noise Troubleshooting
I just recently started hearing a louder exhaust sound that seems to be coming from the area directly under the driver / passenger seat (y-pipe area). I have not been able to isolate this sound to identify what part(s) it is coming from.
The noise sounds like a louder narly drone and is very noticeably different at all RPMs
It started after a spirited drive. All of my exhaust parts are broken in sufficiently and have never caused any CELs or any other noise/vibration issues.
Parts:
Berk HFC
Stock Y-Pipe & Mid Pipe
Tanabe Axle Back Medallion Touring Exhaust
Please offer any advise or suggestions. The y-pipe flex joint heat shield started vibrating/chattering at the same time but I was able to resolve that noise.
Possible causes, bad gasket, damaged y-pipe (is this possible), damaged HFC, any recommendations for troubleshooting are much appreciated. The car went from heavenly exhaust note to **** almost instantly.......

The best way to trouble shoot this would be to get under the car when its running and see if you can feel anything around the gaskets or see any damage to the pipes.

I will have to get it on a lift running and take a closer look. It is kind of hard to explain to a shop that it went from loud to a different kind of loud. Hopefully it is a flange leak that will reveal itself and need sealing and not just a damaged internal exhaust component. thx for the advise!
