Yasuni R Exhaust '89-'11

Yasuni R exhaust, most popular zuma exhaust by far. We dyno tested these, and even on a 100% stock machine we saw a 2WHP (50%) gain. These perform excellent with a big bore kit, too. 

Please choose '89-'01 vertical engine, or '02-'11 Horizontal engine. Available with a silver or black silencer! 

Restrictions must be removed for proper performance.
