Big Gun EVO-M Full Exhaust System — Yamaha YFZ 50 (2017-2024), 4-Stroke

Big Gun's EVO-M series has been a staple for over a decade — built to produce noticeable performance gains and a deep, throaty tone on mini-MX bikes and ATVs. Full system fits the kid-sized and entry-level platforms in the Big Gun lineup.

• Mini-MX / entry-level platform tuning
• Deep tone with measurable performance gains over stock
• TIG-welded steel construction
• Closed-course / competition use

This is a 4-stroke exhaust. It is engineered for the 4-stroke engine architecture above and physically will not fit a 2-stroke bike. Verify your engine type before purchase.
