I picked up an AirRaid MIT the other day thanks to someone pointing out the $50 off coupon. I installed it in about 15 mins no problem, and I do like the improved sound when I get on the pedal. My question is about the factory intake tube. That thing has like extra 4 chambers on it. Does anyone know why it was designed that way? It seems to be very inefficient for air flow. Maybe emission or sound related?
