The Stealth 2.0 Exhaust System is an innovative high-flow/low-restriction spark-arresting muffler with a smaller diameter for a better universal fit. 4-1/2" diameter by 12-1/2" overall length. Quiets UTV or ATV exhaust noise by at least 50% with no measurable back pressure or loss in performance. In fact, Dyno test results on some models have actually revealed an increase in midrange power and overall performance. Universal design fits any UTV or ATV with a four-stroke engine. Heat shield included. Honda models require an additional adapter (sold separately).
