Perfect! Exactly what i was looking for!

By   on  Verified Purchaser

Bolted right up! Great quality and fitment.


Nice Product

By   on  Verified Purchaser

Worked perfect for what I wanted to do which was combine both breathers into a single hose running to a catch-can with no T or Y connectors.


Needed a slight modification

By   on  Verified Purchaser

Yes it fit my bike however the metal tubing interfered with the fuel tank. I wanted to route the hose off the front cylinder not the rear cylinder so I could hide it better. Perhaps that's the reason why the pipe hit the fuel tank. A slight modification and everything now mounted up perfectly. Overall it's a good product.
