So much conflicting info out there. The local exhaust shop told me to do my research and find what I want with no drone and he’ll put it on for me. I was led to believe from YouTube I needed separate pipes to keep each cylinder bank by itself for now drone. I ran into someone at target with an 11-14 R/T and he said he has no drone with an X-pipe. He told me he was a mechanic and did everything himself. As long as it’s all same diameter you won’t have drone. So any advice out there?
