Being knew to this hobby I have been buying products good and bad for my Revo truck.I just had to have a dual exhaust pipe for my truck and I bought an rd logics with the double barrel pipes on each side. I installed and tuned it to my Os21 only to find out that it is very loud and takes away from the performance.My wife told me my truck had to loose the loud pipe or she would take my truck away so I did this.I plugged the inside exhaust port on each side of the pipe.The noise level dropped back to nearly stock and I was able to tune the motor back to performance levels equil to the stock pipe.I used vacuum port plugs like used on car manifolds for plugs.:
