my cat is bolt on on both ends?

Hey Rabbit, I want to do the same to mine, can u give me the parts name u used, I want to be able to take it off if I decide to go back to stock. So the Aveo has 2 cats? why? U have those aftermarket headers? is there a difference in the power! I want to do my ehxaust next week so any imfo is apreciated

I only have a muffler on mine, rest is stock. The rest is stock. But on my 09 the first box in the center tunnel is a post/seconday cat.

The stock cat has a flange on both ends. Xiogary's headers go to either of those two flanges depending on which you buy.

Tnks for the imfo.
