Hi everyone. Have a 2012 r/t Classic M6 STP. I’m looking at 2 different exhaust systems right now. 1 7/8” primary and 3” catless mids. Also looking at their 3” catback systems. Both the AFE and SW headers&catless mids are made of 304 stainless. But the afe catback is made of 409 stainless and the SW catback is made of 304 stainless. Just wondering what people’s experiences are with either of these and their thoughts on it. Thanks
