I am upgrading my exhaust this weekend by going to a pair of Vance and Hines "Big Shot" true duals and TTS Master Tuner. I have a pair of Tail Gunner gatling gun pipes (slip ons). I am going to a much bigger bigger baffle, and installing them in the pipes before the Dyno is done.
What sound or performance changes should I see by maikng this change?
Thanks, Dwayne

 

Probably gonna be louder and going larger on the baffle you'll more than likely lose some torque on the lower end due to less back pressure.
