This Retro Race Exhaust System, handcrafted in the UK, seamlessly replaces the restrictive 400 exhaust system, unleashing the distinctive LA Fab sound.
Featuring a megaphone design can with an additional decat header pipe, it enhances the single-cylinder thump. The classic look, combined with a race-inspired design, allows exhaust gases from the single 400 to exit more freely by removing the catalytic converter, producing a deeper, bass-filled tone that will turn heads. As a direct replacement, it connects effortlessly to the original OEM mounting points on the head and foot peg for a secure installation.
Manufactured in the UK from premium 304 stainless steel, this exhaust system for the Speed 400 includes a fully removable slip-in baffle. The attractive brushed finish makes it a standout feature on your bike while complementing its modern classic look.
Our full system also offers significant weight savings over the stock system:
- Stock system: 10.3 kg
- Retro Riot System: 3.25 kg (7.05 kg saving)
This exhaust system has been dyno tested and is safe to run without any engine tune/remap/flash to the ECU.
Included:
Retro Riot Decat Header Pipe
Retro Rumble slip-on
Stainless Clamp
