The RS-2 full system is a potent and versatile design that evolved from Yoshimura's original TRC, engineered to provide increased and better power delivery. With a different pyramidal shape that increases volume over traditional muffler shapes, the RS-2 is a quieter system with a larger core and outstanding performance.

Questions & Answers
This is for a dirt bike, right?
By: Justin Kooker
Yes, RS-2 exhausts are designed to fit dirt bikes, and offroad motorcycles.
Does it fit well for a 5'2" rider
Yoshimura's RS-2 Enduro Series full exhaust system installs in the stock location. You should have no problem using this exhaust with your height of 5'2".
What is the weight limit?
A bike's weight limit has no effect on what type of exhaust that can be used. You would have to examine your bike's manual in order to determine what weight limit it may have.
Does it run on gas?
Yoshimura exhausts are compatible with all types of racing fuel on the motorcycles for which they're listed to fit.
what jet kit works best and what size jets?
2007 Honda CRF450X
Your best bet would be a stage 1 jet kit in the form of a CRF450X Dynojet Carburetor Jet Kit. As to your specific jetting requirements, I can't say for sure exactly what sizes you'll need. No less, the included CRF450 jet kit instructions do an excellent job of explaining how to get a good baseline for your bike's specific configuration. After that, a test ride or two is usually all it takes to get everything dialed in perfectly.
