Barrel Storm Exhaust for BMW R 1300 GS (2025)

The Storm Exhaust for BMW R 1300 GS (2025) is Barrel's touring line, a slip-on sized for big adventure machines, where heat management matters as much as tone. This version is made for the BMW R 1300 GS (2025).

As a slip-on it keeps the factory headers and catalytic section, so the character stays recognisably your bike's, just with more depth behind it. It is the reversible option: keep the stock can on a shelf and the bike goes back in an afternoon.

Build

• Stainless steel 304 throughout, so it will not rust through a monsoon
• High-temperature ceramic insulation to keep surface heat down
• Removable DB killer, so you choose the volume
• Covered by Barrel's warranty

• Free-flow systems can change fuelling. On some bikes a remap gets the most out of the change.
• We are an authorized Barrel dealer. Every unit is genuine, supplied direct by Barrel.
