After a year the extra weight of the Magnaflow system snapped one of the two hanger bands near the resonator/catalytic converter flange.

Does anyone know where to buy or the part#??
Or a possible polyurethane upgrade?

They're not too expensive at the dealer...maybe $5-6/ea? I believe they're called insulators? Can't remember. I replaced all of mine when I installed the MF catback. I used to have a bunch left over (and still may have, but don't know where). The old parts list shows them as 10304424, and $4.28 each. Can't seem to find my new parts list.

Edit: Found the newer list I have. My p/n is correct, but the price is (was) $4.79/ea. However, those are the 6 or so figure-8 insulators. After reading your post again, the donut-shaped rubber O-rings, which I believe are called "front pipe hangers," appear to be p/n 10056770 and $9.72 each. These prices & p/n's are from the 2007 revision of the GM collision parts list for the Impala & Monte Carlo.

EDIT2: GMPartsDirect shows $6.47 as the cost, with the dealer charging $10.55 for the O-ring hangers, and $3.42 for the figure-8 insulators. They usually kill you with shipping, though.

THANKS!
I took off the other O-ring and it is stamped 10056770. I want to get the SS emblem for the front too, so $14 shipping from gmpartsdepartment.com isn't too bad.

I found a local shop here in Dayton, OH www.undercarspecialty.com that ships everywhere and specializes in any part on the chassis. They had the O-ring hangers for $1.43 ea. The local stealer wanted $15 ea. They are the same part# as the 2002 monte carlo.

Um any parts store/ exhaust shop will have them o-ring looking hangers.
