Has anyone else noticed a lot of engine noise coming through their Yoshi plenum? Mine seems to resonate and almost makes the B23 motor sound like a diesel. If I put my hand on the plenum, all that noise stops.
I'm wondering if it's just the thin sheet metal not insulating sound, or if it's some kind of weird resonance in the way I designed the manifold.
