Roadsitalia Exhaust
The Yamaha XJ6 Diversion has always had a clear identity: a practical motorcycle, without excess, designed for those who want a manageable four-cylinder for everyday use without giving up riding pleasure. The 600cc inline engine, derived from the FZ6 architecture but specifically reworked for this model, offers progressive and easily modulated power delivery, with generous torque at low-to-mid rpm that makes riding smooth both in traffic and on longer stretches. The Diversion version, with its integrated half-fairing, adds aerodynamic protection without visually weighing down the bike, confirming the all-round versatility that has always defined this family. You can find all our proposals in the section dedicated to exhausts for Yamaha.
What we offer for the XJ6 Diversion 2009-2015 is a full exhaust system, not a simple replacement silencer. The original exhaust is designed as a single unit with a 4-in-1 configuration: the four headers converge into a single central section positioned under the frame, forming an inseparable assembly that does not allow the terminal alone to be replaced. For this reason our system replaces the entire gas flow path, from the engine outlet to the final terminal, maintaining compatibility with the original mounting points without requiring structural modifications. The mounting kit is included. We recommend installation by a qualified mechanic to ensure correct and lasting fitment.
All models in this category are homologated for use on public roads throughout Europe and Switzerland: the homologation certificate is included in the package. It is important to note that, since the original exhaust on the XJ6 Diversion 2009-2015 is fitted with a catalytic converter, the new exhaust must be purchased in the catalysed version to maintain full road compliance.
Compared to the stock exhaust, the first noticeable benefit is weight reduction: the original components, often oversized for homologation requirements, are replaced by a more compact and lighter assembly. The XJ6 Diversion's four-cylinder has a contained and rounded sound in stock form: with the full exhaust system for the Yamaha XJ6 Diversion it gains a more defined and present voice, with a more open tone especially at mid-to-high rpm, without altering the balanced character of the engine. In terms of power delivery, optimised flow management along the entire exhaust path can contribute to a more linear throttle response and smoother progression, with a greater sense of connection between the throttle and the rear wheel.
Every system is handcrafted in Lombardy, in the province of Bergamo, made to order. This is not mass production: each component is machined and assembled in-house, with direct quality control at every stage. Direct from the manufacturer eliminates middlemen and results in a more transparent relationship both on the product and on after-sales support.
As this is a full exhaust system on a motorcycle fitted with a catalysed original exhaust, the original catalytic section is also replaced. The catalytic converter is available as an option in the drop-down menu on the product page. Choosing the catalysed version results in no fuelling issues or warning lights, although a brief ECU adaptation period to the new system is normal: during the first rides, minor variations in power delivery may occur, which will resolve themselves naturally. Those who opt for the non-catalysed version should consider that fuelling may not be optimal and that remapping the ECU will likely be necessary to get the best out of the system. The non-catalysed version is intended for track use or contexts where road compliance is not required, within the limits permitted by local regulations.
The dB killer is included as standard. It is not officially removable: its removal invalidates the homologation. For those who require further noise reduction, the No-Noise dB killer is available, featuring an internally welded filter that further reduces decibels without significantly affecting performance. This option is also selectable in the drop-down menu on the product page.
Production times vary depending on the period and workload. Updated lead times are always visible at checkout, before order confirmation. Tracking information is sent automatically as soon as the package is handed over to the courier.

In the product list below you will find all available models for the XJ6 Diversion 2009-2015. The differences between variants are mainly aesthetic: silencer shape, material and finish. The catalytic converter and the No-Noise dB killer, where available, are selected from the drop-down menu on the product page. Open the product page of the model you are interested in to view detailed photos, read technical specifications and configure your exhaust system.
