   I have never had a 4-2-1 but I had a 4-1 on me vTR and it was very low to the ground and easy to scrape so be warned, mine was the gmc and it did sound and make the throttle response nice

   4-1 improves high top end speed where the vtr strugles
   
   4-2-1 improves low down power which the vtr is good at all ready
