2007 Chevy Cobalt

The entire stock exhaust is supported by rubber hangers, all of which will be reused with the GMPP system. Some silicone spray on each will help them slip off with only a slight tug. After removing two such hangers just ahead of the exhaust tip, the muffler drops out. The cat pipe unbolts from the cat-back via two studs and nuts just forward of the resonator. (You can see this connection in the far bottom right of the photo.) The resonator/over-axle pipe is snaked out after its own two hangers are undone, one just ahead of the muffler's location and the other just aft of the resonator. This completes the stock system removal-piece of cake!
