Important Notes:

Road Use: Non-homologated exhaust systems may not comply with local road regulations and are intended for race use only. Noise levels can vary significantly, from standard to extremely loud. Please review the specifications carefully before ordering. If you have any questions or need assistance, feel free to contact us.

Build Times: Our exhausts are built to order, with delivery times ranging from 6 to 10 weeks for standard systems and 10 to 15 weeks for more complex full systems. For the latest estimated delivery times, please visit Current Build Times. These timeframes reflect the handcrafted nature of our exhausts, which are produced by a small team in the UK, as well as the high demand for these limited products.

Exhaust Types:
We offer three types of exhaust systems:

1. Slip-On Exhausts: Replace the bike’s original muffler, leaving the mid-section (catalytic converter) and headers untouched. Slip-ons are a straightforward option to enhance sound and aesthetics.

2. De-cat Systems: Replace both the muffler and the mid-section (catalytic converter), while keeping the OEM headers. Offers improved performance and weight savings.

3. Full Systems: Replace the muffler, mid-section, and headers for a complete overhaul, maximising both performance and weight reduction.

Each system is designed to cater to different performance, sound, and aesthetic goals. If you’re unsure which option suits your needs, feel free to reach out—we’re here to help!
