The Austin Racing GP3 De-Cat Race Exhaust System for the 2021–2025 Kawasaki ZX-10R is a lightweight, high-flow upgrade designed to deliver aggressive sound, reduced weight, and a clean race-inspired finish.

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: These 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: A decat system replaces both the muffler and the mid-section (catalytic converter), while keeping the original OEM headers in place. This offers improved performance and a noticeable weight reduction.
  3. Full Systems: A full system replaces all three components: the muffler, mid-section (catalytic converter), and headers. This provides a complete overhaul for maximum performance and weight savings.

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!

Design Updates: As each exhaust is handmade to order, our designs are constantly evolving to incorporate improvements. As a result, the final product may vary slightly from the pictures shown. These differences are typically very minor and represent the ongoing enhancements we make to ensure the highest quality. This adaptability is one of the unique benefits of owning a handcrafted exhaust.
