Ok here is what I would like to know. I hear everyone talking about FMF SST and Fatty's on there Banshee's. And how good of a pipe they are and how much power the gain their bike. And even the 4 stroke pipes being a good buy for 400 EX's and other 4 strokes. Now, I never hear about anyone putting an FMF Gnarly on there 400 Scramblers. Does anyone out there have one on their bike?? I just about put the Gnarly pipe with the Tubine Core II siclencer on mine but I put an Aaen on it. Was this a good choice? Is FMF a really good pipe that you will gain a lot of power with or are the basically just big in to the advertisments? I was just curios.

I've had both an HPD and a Ritter Cycle Pipe on my scrambler. I prefered the HPD pipe due to the pipe routing, and it's on the quad right now. As for the FMF and the Aaen pipes, you won't find many fans in here. They don't seem to make a lot of useable power.
