I have a 1998 catera and it needs a new "Resonator".
I cannot find one on rockauto, partstrain... and so on.
Do I really have to go through a dealership for this?
Note that its on the back-left, 2 inlet and 1 outlet- but I have not measured the mfg diameters yet.
...just called the Stealership and they said it's called the "Resonator" and they want $500+
Any suggestions will be appreciated.
