Need new pipe-want more RPM

(1/4) > >>

Johnniespeed:
 My Gnarly Woods pipe has seen better days and needs to be replaced. I would like a little more upper RPM power as I like to ride at high RPM. Should I get another Gnarly Woods pipe and remove the reed spacer ? OR should I get a Gnarly Desert pipe and leave reed spacer in place ?  I do not race, I only trail ride, mostly wide track and sometimes tight single track.
  I hope someone has tried both the Desert and Woods pipes and is willing to share thier opinion. I am open to all suggestions at this point.
Thanks for your replies. John

John,

Stewart has testing shows the PC pipe with the strongest #'s up top (don't know if he tried the Desert Fatty).

I have the FMF Gnarly & feel it is the best Bottom & Mid pipe, but agree if you want more up top there are better pipes.

Blue Oval is using the Desert Fatty maybe he can give some input.

i run a p/c pipe and stock silencer it seems to pull hard everywhere but i havnt run a desert fatty just a fmf gnarley and i like the pull all the way through top end on the p/c plus i run a rad valve so it all works together well

Purpletj:
I have always heard the Pro circuit pipes are for top end. I use a Gnarly myself.

Johnniespeed:
Ok, without much research , I have decided to remove the Gnarly Woods pipe and install the Gnarly Desesrt pipe.  I am guessing the low RPM power will decrease and the high RPM and power will increase. I have always liked the Gnarly Woods pipe, but didnt like the absence of high RPM, compared to the stock pipe.

Its almost warm and dry enough to ride in Michigan. ( if the rain holds off )
