i saw something like that on trucks once, but it was basically a dump that would bypass the mufflers completely, making it a straight pipe basically.


And FWIW, i don't think there's any sacrifice in performance for the setup on the vette!



Exhaust cutouts are a bit different from normal valved units.

Pretty cool though.
