I have a 2006 Fatboy. I absolutely love this bike. I am ready for an upgrade though with the exhaust. I have been told by many that for performance, a 2-1 is the way to go. I want two things, performance first and then sound. I have been looking into the Pro Pipe and the SuperTrapp 2-1 SuperMeg. If any could shed some advice on which is better in both performance, especially low end torque, and sound I would greatly appreciate it. Thanks.

 

I can't tell you which is better, but I can offer a little info on the pro pipe. My buddy just put them on his RK Custom. They look good and supposedly give you about 17% power increase. He said he can definitely feel a difference, and he is pulling away from me a lot faster than he did before. Now, I don't know what you want from the sound. If you want loud you might want to look elsewhere. They have a low rumble to them but aren't as loud as the SE slip-ons, with modified baffles, he just took off.
