Engineered to offer a clean look while adding a bit more body to the exhaust system, these reverse cone slip-ons give you that classic cone style with a sound to match. Because of the expansion of the exhaust gasses in the conic-shaped muffler, these slip-ons add deep tunes to the sound of your bike without becoming noisy. 

Handcrafted from high-quality 304 stainless steel and is available in either a brushed stainless finish or a ceramic black coating. They come with all the hardware needed to bolt onto your bobber’s stock headers or any X-pipe by using the original mounting points on your frame.

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

Please note, the bike in the videos doesn't have a catalytic converter. 

Our reverse cone slip-ons come with removable, open DB Killers which are held in place with M5 bolts within the exhaust exit. 

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
