I just bought a 07 vtx t model. witch is the same as a R model. I put cobra long shot pipes on it. I all so put a dynojet power commander III on it. I canĀ“t get it to sound right. When you get to hight rpms it sound like a 4 cylinder with out a muffler. Idleing it sound good. I have allso run it with the baffles and with out the baffles. And that did not help. my question is how can i fix the sound.
