Another version of N20 dual exhaust, vortex muffler was used as the resonator and also acts as a Y-pipe.

vortex mufflers are unique due to the combination of chambered and straight through perforated design. the intent is to have a simpler system (resonator and megan mufflers only) for flow efficiency. heres a review from Stacey David:
