"I just installed my Thunder Monster baffles on my Fat Boy. What a difference! I can feel the power. I mounted the Thunder Monster baffles into the pipe approximately 12" well over the 3" minimum you suggested. I have been an automotive service tech for over 30 years and have raced almost everything with an engine. I never expected this much of a change from an investment under $100."
"I bought a set of Thunder Monster baffles for my V&H Big Radius, followed the instructions and all I have to say is WOW! I love the sound, throttle response is right there, and I love the mid range boost!! I have a couple of friends now who are ordering them."
