This weekend, my car got noticebly louder in cabin..... not sure if it's louder outside. I only have a z-tube which was installed last year and everything else is stock. I looked online and people refer to this as a "drone", loud audible montone sound in cabin between 2K-3K RPM.....

Only thing I can think of is hole in exhaust or something wrong with my cat which I really hope not.....

Any experience with this anyone? Thanks

 

I have test pipes and Z-tube and absolutely no drone whatsoever. I'm 99% sure you have an exhaust leak.

 

You're right turns out right at the muffler connection it cracked right off......

anyone know if I can swap in a 2007 350z mid and muffler? I have a 2003 g35 coupe 6mt.

This one.

dude I was about to say your exhaust isn't stock? based on the notes it was putting out I thought you had an aftermarket but I never looked!

 

lol it is stock, guess it's been leaking for a while and finally just went........ first the radio then the muffler, geez........
