Yesterday I had a flowmaster 40 Installed on my 4 door prerunner. Its way to loud for me. Especially inside the cab. Tomorrow I am having the muffler removed. I am thinking of installing a 60 series. Does anyone have a clip of anyother sounds other than flowmaster. I just dont know if the flowmaster is for me. I want something that is not to deep. More of just a street type muffler. Does anyone have a clip of how a apexi sounds on a 3.4?
