My son has a trx 90, and we mostly ride in the dunes. Wanted to know if intake and exhaust is worth the money and what brand of exhaust if best for that bike?

 

has anyone put exhaust on a trx 90?

 

For Christmas I bought my son a Pro-circuit pipe, I also got a K&N airfilter for his 06 trx90. The parts are installed but we haven't been able to ride yet due to the weather. We have a trip planned to Little Sahara Oklahoma in two weeks weather permitting. I'll let you know how it works, as we normally just ride in the sand as well. I am also planning on changing the main jet size up one or two. It sure looks and sounds better, I'll let you know.
