This part worked well and delivery was fast. I was hoping to only have to replace that part, but the flange on the existing exhaust that connects to the resonator was much smaller and didn't seal well. I think the rust has just worn away from the edges. Replaced the rest of the exhaust. It was necessary anyway, so it wasn't a bad thing. I have uploaded several photos, one shows a bad gasket, another an old flange and a third the job done. That was a 2004 Malibu Maxx with a V6 engine, by the way.
