- Kawasaki W650 (1999-2007)
- Kawasaki W800 (2010-2016)
- Kawasaki W800 std/Street/Cafe (2019+, Euro4 and Euro5 versions)
Stainless steel 2-into-2 exhaust line with side outlets.
The dB-killers are integrated within the pipes for a complete look. The pipes are double-layered, with a layer of soundproofing sandwiched between two concentric steel pipes. Diameter 60mm at their widest. The conical shape of the downpipes also allows a better "outdraft", hence a faster exit for the exhaust gases and a performance gain.
For the newer W800 from 2019+, available as an option in "Euro4 certified" version, in this case the baffles are replaced with two mini-catalysts in the downpipes. In this version the system is supplied with Euro4 certificate.
Does not exist with Euro5 certification.
For W650 and the non-cat W800, certified "Euro 3" (with dB-killers in place), supplied with E3 certificate.
Available in polished stainless steel, brushed stainless steel or ceramic black (powder-coated then baked in 300C autoclave oven for strong resistance).
Weight only 5 kg, less than half of the original exhausts.
Noise level intermediate 3/10, one step louder than stock with a more "direct" sound. Removable baffles. Sound video here.
The baffles/catalysts are easily removed if you want a bigger soundtrack, but in this case you lose the legal certification.
The downpipes include the locations to re-fit the O2 sensors.
No modification of the engine management required, the ECU will automatically adapt the map to the new parameters.
