To be honest the original mushroom filter whistled so much when I touched the loud pedal it became annoying.I've got a vid on YouTube......ill post a link and you'll see what I mean
I had a selection of filters to hand including a mammoth cossie style one. The twin
had been laying around in a box with a flexi fan for ages so I offerred it up.
I'm hoping that the empty space inside the crossover pipe and the area inside the twin
filter arrangement will make it a little quieter........that's the plan. Hoping to get some more fresh air into the filter are too .the turbo set up isn't really tunable so I'm grabbing at anything I can .feel free to tell me if i'm making a mistake tho
