The stock trumpet is a tuned velocity stack.

Generally speaking, velocity stacks are used directly over a throttle body where straightening out the air flow would be very beneficial.
Our "trumpet" pulls in air which then makes a 90* turn and runs into the filter. Is this design more for efficient air flow or more for noise abatement? |

Given the locations of the resonators, definitely noise abatement

Please don't indicate I made an improvement. I made a change for my own fun.
