so you clearly R not a big fan of dynoport. thats ok with me, but im still queries on which pipe you tried. i dont know if ether pipe they make for the k5 looks big.

did the pc 2 pull harder in the mid-upper rpm rang or was there another reason you liked it more?  at what rpm did the curve sign off compared to the other pipes?

stewart:
i am not a fan one way or another ,,,but the dyno port pipe did not perform  well all the way thru the rpm range ...pro circut has a handle on the k 5s pipe ,,,they have done a great job  getting as much primary length and the diameters as will fit the bike

kwakman:
I've been looking into this myself for top end gains.PC say plat 1 for top end and i agree after much checking of details and scrutinization. Go plat1. or do you want an FMF Desert?????????????????????????????????????????????????????????????????????????????
 No seriously, plat 1 is the way forward.....I hope, ordered one.

bigbellybob:
i know its apples and oranges but on my bike ktm380 the pc 2 signs off a lot earlier than the the fmf fatty and my stock pipe.

and it looks like i need to give up on finding out what dynoport pipe Stewart tested. or why he feels the pc2 is better for mid/top

KXcam22:
Thanks for the info Stewart. The dyno doesn't lie (as long as its always the same dyno).  I have owned many pipes that changed the power characteristic greatly but not the overall horsepower.  It gets you thinking that "wow this thing flies" and then your buddy passes you.  I built a couple of pipes from scratch for a roadracer and it is an art to get all the required lengths to fit on a bike.  You have to hand it to guys like PC and FMF.  Cam.
