I recently wanted to purchase the exhaust silencer and the resonated exhaust tips that Ark performance produces in order to reduce the low rpm humming sound and highway drone(2000-2500rpm). I sent an email to the sales department of Ark, and they recommended me to get the HF cat front pipe to replace my resonated front pipes instead of buying the tips and the silencers. I wonder which one is quieter? I always thought the HF cat would be much louder compared to the resonator. What is your guy’s opinion?
