Attention : Not compatible with a center stand (if your bike has one, get rid of it and use our workshop stand, a much smarter solution !).
Exhaust line 2-into-1 with short silencer, similar to a Zard Cross system.
100% stainless-steel construction with removable baffle.
Available in polished stainless steel, brushed stainless steel or ceramic black (powder-coated then baked in 300C autoclave oven for strong resistance).
Weight only 4 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. Certified "Euro 3" (with dB-killers in place), supplied with E3 certificate.
For EFI bikes the downpipes include the locations to re-fit the O2 sensors - these can also be eliminated with this kit.
This video (here) will give you a good idea of the sound produced.

It is recommended to perform a carburetor/injection adjustment to maximise the gain in performance and sound.
