I wonder what this 3 small pipes are for,, what do they do or can you skip those?
Can't claim to have the knowledge off of my own back on this, but as it happened Mark at VAGManchester explained the resonator on the exhaust and used a picture like this as an example of what manufacturers do to reduce resonance of unwanted exhaust noise at different frequencies.
So in short its to dampen intake noise. The reason there are 3 different sizes, each one will be sized to reduce a certain frequency of noise.
Another opportunity for a resonator delete then
They're called Heimholtz resonators, used in all sorts of applications to reduce various noises. They are also sometimes used to reduce intake turbulence.
