09 WR450 exhaust upgrade advice

4 posts in this topic

I want the exhaust that gives my bike the most power it can get from an exhaust. Noise doesn't matter and let's say price doesn't matter either. Y'all give me a list or tell me what ya got and how it works.

I say run pretty much any open perforated core exhaust you end up with. You may or may not feel the difference from one to the other. If you want good usable power send your carb off to Zipty racing and get all the mods done. Especially the emulsion tube mod.

Most aftermarket open exhausts will give you similar performance improvements. I love the DR.D system as it seems to better tuned for my bike, but you really can't go wrong with any open system.
