Just what it says. What's the major difference between the FMF torque pipes and the SST pipes. I want more mid to topend so which would be better and I also like them noisy but that's not really important unless the SST is designed to give more power and be quiet. Also which silencers or spark arrestors should I use that won't hurt performance. I'm thinking about keeping spark arrestors since I may go riding in the national forest one day but I'm not sure if I ever will.

 

VENOMOUS,
The sst pipes are for mid-high rpm range,the torque pipes are for mid mostly,but do help the top some over stock.The sst pipes are supposed to be used with sst silencers which are about three inches shorter than power core II's so you know they will be louder.I have a friend that has them and loves them.They sound kinda like toomeys but are a little deeper.

 

I dont know about the Torque pipes but I run the FMF SST's. They are a great all around pipe that imporve low to top end power.
I have noticed my powerband has increased tons throught the rev range in all gears, explosive power in mid as well.

Im happy with mine.
