Pro Circuit Quiet Insert With Spark Arrestor Pro Circuit Quiet Insert With Spark Arrestor TRX400EXrider 5 out of 5 stars Couldn't be any easier "Put this on my machine in about two minutes. It definitely dropped the sound volume a noticeable amount without any loss in power, and it still sounds good. I am not a pro or amateur racer so the power change might be noticeable to others. For my purposes this was exactly what I needed to quiet the ATV yet keep my performance high. It was simple to install and if I want to remove it that will be easy too. Definitely recommended."
