Catalyst Replacement X-Pipe – TRIUMPH Street Twin 900 / Speed Twin 900

Unleash your 900 twin: more torque, less heat, clean and simple install

Designed for modern 900 twins, this X-Pipe replaces the stock catalytic element located under the frame. By optimizing exhaust gas flow, it delivers crisper throttle response, stronger mid‑range torque, and a markedly improved mechanical feel. The result: a livelier, more enjoyable, more expressive bike while retaining a perfect fit in the original location.

Made from stainless steel, this X-Pipe is engineered for a plug & play install with no heavy modifications. The mounting points and footprint follow the stock header routing, simplifying installation and ensuring precise compatibility with your 900 twin. Whether you want to reduce heat build-up under the bike, gain smoothness, or restore a more natural sound, this part is the logical upgrade to the exhaust system.

On the road and in daily use, the benefit is immediate: better breathing, stronger roll‑ons, and a freer‑revving feel. The X architecture balances pulses between the two cylinders for smooth behavior and a rounded tone without unwanted drone.

Compatibility:

• Triumph Street Twin 900

• Triumph Speed Twin 900

Technical specifications:

• 🛠 Type: Catalyst replacement X-Pipe (center section under the frame)

• 📏 Dimensions: same footprint as the stock unit, fits the central location

• 💪 Material: stainless steel (durability and corrosion resistance)

• 🔩 Installation: plug & play on the stock header, compliant mounting points

• 🎯 Flow optimization: X architecture promoting pulse balancing and gas velocity

• 🧰 Maintenance: low maintenance, easy cleaning

• ⚖ Weight: around 1.8 kg (lighter than the stock catalytic unit)

Advantages over stock:

✔ Stronger torque and better mid‑range roll‑ons
✔ Notable reduction of heat under the engine and near the legs
✔ Fuller, more authentic sound without annoying resonance
✔ Quicker throttle response and a freer engine feel
✔ Lower weight compared with the stock catalyst
✔ Reversible install with no heavy modifications

Why upgrade the stock part?

The stock catalytic element, while effective at filtering, creates significant back pressure. On a 900 twin, this results in more heat accumulated under the frame, added weight, and a strangled engine feel, especially at low and mid‑range. Over time, this restriction can also diminish day‑to‑day riding pleasure.

• High back pressure that restricts gas flow

• Heat build‑up felt near the legs and under the seat

• Additional weight without performance benefit

• Less decisive throttle response and weaker roll‑ons

This X-Pipe cleanly replaces the catalyst, streamlines gas evacuation, and balances pulses between cylinders. You get a more responsive, torquier engine and better‑controlled temperatures in the central area, while maintaining a clean, reversible integration.

Ideal use:

• Riders seeking more smoothness and responsiveness every day

• Touring and leisure riders wanting to reduce heat under the bike

• Roadster/café racer builds seeking optimized exhaust flow

• Riders wanting a rounder tone and better presence without excess

• Users seeking a simple, reversible, and durable exhaust upgrade
