So a local muffler shop has a 3" full stainless steel cat back exhaust system for sale that they took off another customers SRT. They said they think it was a 2012 or 2013 model and it was some kind of upgraded system from Dodge. Anyone familiar with what the system could be? We couldn't find any part numbers or branding on it. They only want $425 installed for it and they said I would get a little bit of performance gain compared to my stock 2010 RT setup with just a resonator delete.
