I tried Rolling Thunder slip-ons with 1 3/4" baffles whats nice is you can purchase new baffles up to 2 3/4" for 60 bucks a pair.The company recommends remap if you go above 1 3/4" on the baffles. Love the new sound and was very easy to put on.My .02!!
SE IIs torque are what you want. They are a louder then stock but quieter then the regular SE and SE IIs.
What are you putting these on? I have a pair of New SEII torques I may need to sell that i replaced with normal SEIIs cause they were not loud enough for me (wife's bike)
