Barrel Bass Master B-20 Exhaust with Decat & Sub-Header Pipe - Royal Enfield Bear 650

Built for the Bear 650 Twin Engine

The Barrel B-20 Bass Master Exhaust is engineered specifically for the Royal Enfield Bear 650 platform. This is not just a slip-on, it’s a performance-focused system with a decat pipe designed to unlock the full breathing potential of the 650 twin engine.

Now Supplied With the Sub-Header Pipe

Barrel has made the sub-header pipe standard on this system, and it is included in the kit at no separate cost. Earlier versions of the B-20 were supplied without it. This is the complete, current specification.
