Stainless steel 2-into-2 exhaust system 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.
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.
For 2001-2016 bikes, the system is certified "Euro 3" and supplied with E3 certificate.
For 2016+ bikes, the system as standard is not certified, but you can take the corresponding option to have integrated catalysts. In this case the system is supplied with a Euro4 certificate.
The downpipes include the locations to re-fit the O2 sensors if you bike has them (2008+ versions) - these can also be eliminated with this kit.
This video (here) will give you a good idea of the sound produced.
Designed and crafted by MASS Moto in Italy. MASS is a small company that combines passion and high technology to produce products of very high quality and perfect finish. All MASS products are made of aviation-quality stainless steel and are type-approved for Europe.
We recommend fitment by a professional, unless you are experimented in such things.
Requires no modification of the bike, totally reversible assembly.
We recommend to fit a high-flow air filter with this exhaust, to balance the air in/out of the engine. It is recommended to perform a carburetor/injection adjustment to maximise the gain in performance and sound.
