OK its time to do a little work to the exhaust system... For now I am going to keep the 3 inch system but replace the muffler and eliminate the resonator. What muffler would you guys recommend? I am not really interested in getting volume and don't want the dreaded drone
. What I am looking for is about the same noise level in the cab with increased performance.
