I have t6 pipes on the banshee I have now and I had another banshee a while back that had fmf sst pipes. They were fairly close as far as power goes but the toomeys look better and sound 10 times better in my opinion. To run the t6 pipes you don't have to remove the coolant resevoir or use the airbox vents, they are so little I didn't even bother using them. Since you have the silencers for the fmfs I would just try to get some used sst pipes somewhere, I don't think you will be disapointed because they were a good all around pipe.
