However like most things there is a bit of a trade off the right bend pipes will give you power much more power than leftys like the pipes shown in the graph as far as leftys are considered the toomey dominates. All the righty's will give a very similar increase to the toomey but more through out. However for the most part you sacrifice this much desired power, for duribility to resist a pounding of roost with rocks. However unlikely you should end up behind this person because of their pipe body is less protected from the plastic, frame and other factors. Which is why the YAMAHA compay decided to have their blaster pipes bend that way they wanted durability and quicker power than the glam and flash that the pipe companys so willingly give away. Hence the quicker power the graph shows but anything after 3rd it's easily left behind the others. So thats why I chose the toomey as my first blaster pipe but if I had to chose another I would happily chose the LRD specialitys pipe so there's your history lesson good luck.................
