Does anyone know if they found a bad cat converter,
will they replace the whole front piping (which I believe includes the resonator) before the muffler (163 490 91 14)
or can they just replace a cat converter itself?

I think I have a bad cat converter because I hear the rattles right underneath driverside when idling and also I smell exhaust when exiting/entering the car.
Does that sound right to you guys? BTW it is for 01 430.

I had the resonator taken out so I am wondering what are they going to do.

Any help wiil be appreciated.
Thank you.
