I bought a 2009 Cobalt from my son as a starter car. The vehicle has a bad exhaust leak I have isolated to the exhaust flex at the manifold. I was looking at a replacement online and found they come in 2” and 2.25” sizes. The Cobalt is a LT model. Any ideas as to the size I need? The exhaust is stock.

So it seems you want the 2" version.  
The sportier SS trim will use the 2.25".
