Hi i was trying to find a replacement resonator for my cobalt but it doesn't have any branding on it and it has 2 3 bolt flanges on it. but I can only seem to find resonators with a single flange or no flanges at all. I have the ZZP catless downpipe and had the ZZP muffler but its not a ZZP resonator. Anyone know someone who makes 2 flange resonators for the cobalt? both flanges have factory welds on them so it doesn't seem like a home brew part.

Only exhaust for these cars that I know of that used all 3 bolt flanges is what I got, Modern Performance. Their resonator specifically has 2 3-bolt flanges, with maybe 6" pipe pre and post resonator before said flange.

Just find any resonator that will fit between the flanges, then take it to a weld shop and they can cut the old flanges off and weld them onto the new resonator.

I can almost guarantee that will be cheaper and easier than tracking down and ordering a new pipe section.

This. Have the exhaust shop put in the largest resonator that will fit.

And the reality is that you don't need to keep it double flanged. The OE setup is to only have a flanged connection with the downpipe.
