2003 Aztek Exhaust Part?

[smayfield]

Hi... the rear part of my exhaust just fell off.... not sure if it's a 2nd muffler or a resonator or what... but it's south of the real muffler at the rear doors. It is stamped with a GM part number 8MX-BOX00185-02... the first "O" could be a zero, hard to tell. The first 8 is definitely different from the B in the 4th position. Tried all the combinations though and can't find a reference for what part this is. Any idea? Car sounds fine without it though, so I don't THINK it's that important.

It is a muffler and make sure the exhaust gas isnt hitting the gas tank.

Is it #4 on this diagram? If so the GM P/N is 15252914 but is discontinued by GM. Rock Auto lists a walker replacement. but it makes a difference what year your Aztek is, and if it is a base or rally model, FWD or AWD also makes a difference. Either way an aftermarket replacement should be available. Good Luck
