Does anyone have any experience replacing the giant boat anchor of an exhaust/cat on the TNT 600? I purchased a very nice quality two into one pipe on AliExpress and paired it with some Delkevic carbon exhaust that I already had. It looks great but performance has deteriorated a bit. Since to the best of my knowledge you can't get a power commander for the TNT 600... any other ways to adjust the fuel/air mix? I've already experimented with several different baffles as I think a lack of back pressure from the new pipes is the culprit. Any thoughts or advice would be greatly appreciated. Thanks!
