Exhaust system for the 2016+ ND Mazda MX-5 Miata designed by Fujitsubo. The Fujitsubo Authorize RM Exhaust is a rear muffler section with titanium tips and offered with a rear lip. The Fujitsubo A-RM transforms not only the sound of the ND Miata, but also the looks as a Kenstyle Rear Diffuser is included. The Fujitsubo A-RM exhaust features 70mm quad slash cut exhaust tip with blued finish that is accentuated by the new rear lip, though some modification to the factory rear bumper is necessary. The new exhaust from Fujitsubo is 1.6 kg lighter than factory and features 50mm piping.
