pc platinum 1 or 2 final answer
dnmac1999:
Hey bigbellybob, I bought that Dyno-port off stewart. It is the mid-top end pipe.
bigbellybob:
im sorry but what info did Stewart give us? the dynoport pipe he tested was down 5hp, OK i believe him but with out knowing which one of the 2 pipes dynoport offers was down 5hp is worthless info.
and the fact that he likes the pc 2 with out telling us why is useless too.
i think he is saying that the k5 likes a longer section before the divergent cone section but that's not very clear. how much dose it like, how much more dose the pc 2 have over the pc platinum or other pipes? non of his info helps me decide if one pipe favors the mid and upper rmp range over another pipe. and if he is saying that the pc 2 is better for mid/top why would pro circuit have this in the description of the pc 2.

--- Quote ---The Platinum 2 pipe was made for people who ride or race off-road. Constructed from heavy-duty 18- gauge metal, it offers increased protection from rock or crash damage. Like the Platinum and Works pipe, the Platinum 2 offers incredible performance with substantial power gains in the low and mid range part of the powerband.

to me this sound like the pipe was designed for low to mid power not mid to top. maybe the dyno showed something different but i have not heard Stewart say that the pc 2 works better in the mid upper RPM than the other pipes, just that he like it.
