Weighing in at 3.1 kilograms, these slip-on mufflers are engineered to offer a subtle yet deep sound to your Speedmaster. They fit directly onto the stock catalytic converter as well as any X-pipe.

Handcrafted from A-grade 304 Stainless Steel, these slip-ons offer a distinct aesthetic thanks to a slightly upswept look when mounted, and the option to go for either a brushed stainless, ceramic black coating or polished finish. In both cases, the aluminium end caps contribute to the unique look that will stand out on your Speedmaster. 

Due to the conical shape which allows us to pack the slip-on with ACOUSTA-FIL®, your Speedmaster will get a deeper exhaust tone compared the stock system, and is a quieter option than our drag pipes.

Please pay careful attention when selecting which model of Speedmaster you have:

• For bikes classed as ‘Pre-2025’ the OEM silencers are held into the cat with a gasket.
• For ‘2025 Onwards’, the link arms are welded to the cat.

If you are unsure which model you have, please check this guide
