Playing on the dyno today confirmed that my Powroll Supertrapp setup that has served me well with my 110cc Honda build is holding my 151cc Jialing motor back. The pipe I used to prove this was a CRF70 fitment CHP Ultima.

Of course, this means I need a new pipe. : )

The original list of contenders I have considered at one time:
CHP Ultima
Akrapovic CRF70
FMF 4.1 (only available in a 50 bend)
TiForce (only available in a 50 bend)
Procircuit T-4

Most of these pipes were designed expecting a 124cc motor at the most, usually shooting for something far smaller. I know the Ultima works, but I didn't have any of the others on hand to compare to, is there a better/bigger system available that'll let a 151 breathe properly, or is the Ultima still the Ultimate for minis?

Try a Titanium Pipe... I just got a new Pro circuit Titanium T-4 for my bike...

KSKENE247 · 08-18-2007, 07:10 PM

you should try some of the chiner pipes to see how well that acutally claim to be... like the hbomb and the new sgr pipe..

Kurlon · 08-18-2007, 07:17 PM

Let me qualify this, I'm only going to buy one pipe. : ) If people want to lend me pipes to test with, cool, but I can only spring for one out of my pocket.

KSKENE247 · 08-18-2007, 07:24 PM

hbomb... if it performs as sik as it sounds that would be tite

AHPminis · 08-18-2007, 07:44 PM

I have a pipe here I will send you to test with if you pay shipping, if you like it, keep it and pay for it and if not send it back after you test with it and share the results.

Jeeeez !!!!!

No wonder I can't keep up with you guys at Rt 106 with my little 88 motor !!!!!

No but seriously .... I truely think that the stock 50 pipe flows the best !!!

T Bolt USA · 08-19-2007, 05:03 AM

heres a few we offer for big motors

chp ultima
h-bomb (new bend)
and comming soon x-core

first thing i would consider is using a 32mm header over 125cc

boxy · 08-19-2007, 05:29 AM

go the h-bomb. awesome performance and note.

micro75 · 08-19-2007, 06:02 AM

From are testing the Ultima is the top big bore pipe we have run the H-bomb after we got the bend right and made a new rear mount the pipe worked decent the x4 pipe would be a good choice if you could mod it to fit hope this helps also we have ran the FMF and it was not close to the Ultima in performance on are motors

Whelp, my Powroll unit is a 28mm ID, non-stepped, looks like Arkapovic's is 28mm ID after the step, 24mm initially, so it's right out.

Anyone got ID data for the other pipes? I assuming CHP's Ultima is 32mm at some point, and the H-Bomb matches it?

all three i mentioned are 32mm headers

the larger mfg like fmf and pc are building 50 pipes
there good products
but were starting at 120cc now

Kurlon · 08-19-2007, 10:44 AM

Has anyone compared 110 pipes to see if they run larger headers? (I'm going to have to do some mod work to mount most of these pipes anyways as they aren't available in 70 setups, why not mod a 110 pipe if it gets me more flow?) KLX's have been running larger displacements for awhile, I'd assume the headers have evolved to match?

kezajones · 08-19-2007, 11:19 AM

find someone with a pipe bender and be nice to them

HACKMUNCH · 08-19-2007, 11:56 AM
