pc platinum 1 or 2 final answer

[slow600]

as title implies. im ready to buy a new pipe and silencer. 304 is already locked in, need to know which pc pipe to get. looking for more mid-top end. thanks

the pc platinum is just a chrome works pipe and probably better for what you want out of it. it will give gains in all RPM ranges. the pc platinum 2 is heavier (thicker metal) and increases low to mid power. if you really want mid/top you could look into a dynoport, they have a mid/top k5 specific pipe but its $400

[slow600]

is there a website for this dyno-port pipe? i had been reading everybodies feedback on pipes....including stewart, and this is the first ive heard of a dynoport.

[slow600]

nevermind, told middle of march before they could even start making one for me and its raw only.

[stewart]

the dyno port pipe  i tested was the lest powerful pipe i have dyno'd,,,,,down  5 hp  ,,,the problem with the dyno port pipe is its to short from the port of the head out the single cylinder 500 two strokes like the longer distance  of the pipe  out to the chamber the dyno port is very short here

[bigbellybob]

Stewart what dynoport pipe did you test a big volume or a mid top?

[stewart]

it did not look very big

[slow600]

sooooo, 1 or 2?

[stewart]

 the pc 2 was the one i liked,,,,,,,,,,,,,let me add why  this later in thread sorry for not enough info,,,im not saying dyno port is good or bad but they really missed it  on the k 5 pipe i tested

[slow600]

thank you.

[bigbellybob]

it did not look very big

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.

the pc 2 was the one i liked

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

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

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.
