Hey guys can someone help me out? Just changed stock cats they had gone bad so i went with Magnaflow i have there exhaust on my G and love it. But after the change check engine light still comes on and reads left cat is bad my mechanic says it beacuse the cats don't have enough metal. So does one of you knowledgable DODGE FANS have any thoughts.
