is this pipe worth its money? because I saw one on rockeymountain ATV for 225 dollars... or is the FMF Gold Series Pipe better?







thanks!!
 
The sst will give you more top end and nly top end. I have a SST and a Factory fatty for a CR125. I tend to run the Fatty more often. It gave me a more useable powerband. Unless you run constantly on the top, the fatty adds to the low-mid range.
 
I thought:
-SST is for MX, more bottom and midrange power, only litte more on top
-Fatty is street and little more midrange and much more on top.
???

Can I use the Q-Silencer on SST and on Fatty pipes?
 
get the fatty more acc and you caint use the Q silencer you can only use an sst silencer plus the fatty is 163 at motosport.com right now i really like the fatty much more my self i can beat a blaster with an sst and he has more mods then me
 
i mean you caint use a q silencer on an sst pipe but on a fatty you can have the q and more other silencer's because if you going for mx the powercore 2 is the way to go but on trails the q is nice

I'd check that out. My cr125 and 250 both have fatty with Qs. My cr125 also has a sst pipe on the shelf and I have ran it with my spark arrestor. Maybe different with blaster, but it doesn't make much sense to sell pipes that don't exchange for specific conditions. The FMF website doen't even say that it won't fit.

Plus the SST gave my bike what they claim it does. It increased the midrange gains and extended my rev limit/ high output. But I don't run with the throttle pegged that much. The Fatty gains are similiar through the mid and a shorter range up top. But it eats the grits down low. Throttle response was better with the fatty also.
 
so the fatty and powercore2 is a better setup than the sst and the poowercore2 sst?
for trails when you need more low and mid powerband yeah??
