I can't comment as to which is better as they are both near identicle in performance. We got +8HP and +12TQ, and NW reported +8HP and +8TQ. Ours is a two piece hand polished pipe, their's is a one piece welded and powdercoated pipe. Our filter is located behing the lower grille, theirs is located behind the upper grille. We offer an optional MB Engine cover. All in all I'm sure either product will put a smile on your face.
