Barrel Outlaw 2.0 Exhaust for Kawasaki Ninja ZX-4R and ZX-4RR

The Outlaw 2.0 Exhaust for Kawasaki Ninja ZX-4R and ZX-4RR is the current Outlaw, a 72mm chamber aimed squarely at inline-three and inline-four engines. This version is made for the Kawasaki Ninja ZX-4R and ZX-4RR.

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
• Supplied with mounting clamps

Good to know

• An aftermarket exhaust is louder than stock. Check what your local rules allow.
• 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.
