I thought the purpose of that side tube was sound suppression. You call it a resonator but what does it do if it doesn't suppress sound? Is it just for additional volume?
Separately, what does the turbo sound you are hearing sound like? The sound I am hearing is sort of like air vibrating a reed, but it does seem to rise and fall with turbo boost pressure. That's the best description I can come up with.
