what is this pipe good for

fmf are average pipes right novis how do you like yours?? im thinkin on gettin a shearer but i know that theres better pipes for than the fmf...
 
the sst pipe is a high range pipe. the fatty is a mid range pipe and the gnarley is a low range pipe

i'm not sure i'd call the SST a "high rev" pipe.. i've sen SSt's sign off before a fatty.. that was on a banshee setup though not blaster..
