This winter, I installed a SE 103 with SERT on my 09 FLSTC. Have been told that I could get more performance out of this if I put on a good 2-1 exhaust. Currently running Rush Slip ons. Have been studying up on this and as you know, there are many that claim to be the "best". With all of the knowledge on this site, I am looking for some input on the "best" 2-1 performer for my application. I am hooked on torque and low end HP.
