i know this is beat to death. but i have been looking around for a while and i cant find a sound clip of the flowmaster 40. for the cobalt ss/sc. if anyone has one or knows where i can find one that would be a huge help. thanks

 

I have heard it and I would say don't bother with the original 40. Consider a Super 40 b/c it's deeper, outflows the original 40 and it will make for more comfortable driving. If you don't want the Delta Flow Muffler (which a Super 40 is) then you can get a Flowmaster Muffler with the original 40 design with the 5" thick case.

 

I had a V-Force muffler on my 2.2L HHR. It sounded sweet. It's almost like the super 40.
Just removed it today to install sidepipes.
