Monster 937- Indy Race silencer with carby end cap

Description

The Arrow Indy Race ECE Homologated Silencer Series offers a premium performance upgrade compatible with all original components, making installation simple and fully reversible. Available in two versions—Titanium (71393PK) and Aluminium Dark (71393AKN)—both models deliver improved sound, reduced weight, and a refined racing look while staying street-legal under ECE regulations.

Each silencer features a carbon-fiber end cap, a compact 250 mm body, stainless-steel internal components, and a durable welded-mount design for secure fitment. The included DB Killer keeps the exhaust compliant while still delivering Arrow’s signature Indy Race tone.

For riders looking to enhance performance further, the system offers an optional 71767MI Non-Catalyzed Stainless-Steel Mid-Pipe, replacing the restrictive catalytic link section. This upgrade increases flow, deepens the exhaust note, and improves throttle response while remaining fully compatible with the OEM header and Arrow silencers.
