This MBRP exhaust system is great for ATV enthusiasts who like to explore trails on their 1999 - 2007 Honda TRX400EX Sportrax. It bolts on quickly, so you can spend more time on the trails and less time installing. The exhaust gives a nice, balanced sound that won't be too loud when you're cruising all day, but it can also make an aggressive sound when you slam the throttle. It's a great addition for anyone looking to enhance their ATV's performance and look.
