X-Pipe + Mid Pipe for Triumph Motorcycles (2022+)

Removing the cat shifts the power band. The Euro 5 catalytic converter adds restriction to the exhaust system, and that restriction helps exhaust scavenging in the 2,000 to 4,500 RPM range where a Triumph parallel twin does most of its work. Remove the cat, and that backpressure drops. The power band shifts upward: you gain breathing room at higher RPM, but you will likely feel less mid-range pull in the range you use most at street speeds.

The degree of that shift depends on your setup. With the stock ECU and no tune, some riders notice it more than others. With an ECU remap, you can recover the low-end character and improve the overall curve. If low-to-mid torque is what you value most about your Triumph, plan for the tune before you install.

Not required to install, but recommended. The stock Triumph ECU will adapt to some degree, but it will not fully compensate for the changed exhaust characteristics at mid-range RPM. A tune lets you dial fueling and ignition timing to match the open exhaust, recovering low-end performance and cleaning up deceleration behavior. If you plan to run this kit without a tune, be prepared for some changes in throttle response and mid-range feel.

This kit has been tested with British Customs slip-on exhausts only. We are not able to confirm compatibility with third-party aftermarket slip-ons. Slip-on mounting configurations vary by manufacturer, and we do not maintain a list of confirmed third-party fitments. If you are running another brand's slip-ons, we recommend contacting us before purchasing.

Bolt-on. Euro 5 Triumphs have the catalytic converter welded into the factory mid-pipe assembly, which leads some riders to assume the decat process requires cutting or permanent modification. It does not. This kit replaces the entire factory Euro 5 mid-pipe and cat assembly as a complete unit, using existing mounting points with the included stainless clamps. No cutting, no welding, no permanent modification to the frame or header pipes.

Yes. This kit significantly increases exhaust sound. If noise level is a concern for you, this is not the right modification. The decat mid-section opens the exhaust system in a way that produces noticeable volume increase, not just tonal character change.

If you want the quietest possible setup while still running aftermarket exhaust, the BC Predator Pro 2.0 with the DB Killer installed is the lowest-volume option in our lineup. That said, even with a DB Killer, we do not recommend this combination for riders where sound level is a primary concern. The stock mid-section and slip-ons will always be the quietest option.

No. This product is designed for competition use only and is not legal for use on public roads or highways. Removing the catalytic converter does not comply with emissions regulations. Purchase and installation are the responsibility of the buyer. Not available for sale in California.

Yes. Because this is a complete bolt-on replacement with no cutting or permanent modification required, the factory mid-pipe and cat assembly can be reinstalled. Keep your stock parts if you want the option to return to the original configuration.
