MIVV- 2025 Kawasaki Z900
Italian manufacturer MIVV has three choices of Slip-On for the popular Euro 5+ homologated 2025 Kawasaki Z900/SE.

| AK-1 |
The AK-1 is an "elegant muffler with titanium body". There is a Twill Weave carbon fibre end cap, and it has been tested to produce +3.20 hp compared to stock (measured at 9,400 rpm) and +2.00 Nm of torque at 7,600 rpm. The weight is 0.10 kg lighter than stock and the dynamometer curve graph (available on the MIVV website) shows the power gain remaining constant throughout the engine's power range.
The GP PRO is a "compact and aggressive design" muffler, available in two versions (carbon body and black stainless steel alternative). Said to match the lines of this naked sports bike, technically the GP PRO is produced using semi-artisanal TIG welding; the outlet pipe features a removable protective grille that hides the dB-killer.

There is a dynamometer tested +2.10 hp gain (at 9,500 rpm) and +0.90 Nm of torque at 7,700 rpm. The weight is -0.10 kg less than stock and here too, the power gain is consistent and smooth throughout the rev range.
Finally, the MK3 is a track derived slip-on, based on MIVV's experience in Moto3 and Moto2. Described as "the perfect synthesis of racing design, performance, and technology", the silencer body is in glossy carbon, also with a protective grille on the end cap.

There is a +1.60 hp power gain (at 9,500 rpm), +0.30 Nm of torque at 7,600 rpm and a 0.60 kg weight saving – weighing only 1.5kg. MIVV are also offering 'No Kat' 4x1 headers kit for race use that is compatible with the Slip-Ons described and the bike's standard muffler.
