Excellent product.like all the vanasche products.
Top notch.bullet proof.
Great looking pipe, easy install, sounds awesome, much lighter and cooler and bike runs great!
I installed the wings on a completely stock bike. It seemed to be running lean at low rpms so I installed the smaller dB killer and it is running better but still not great. I have a fuel dongle o2 delete on the way until I can get a power commander and have it tuned. Excellent build quality. Highly recommended!
Great all around exhaust, about a 10 minute install
Louder than stock when you get on it, and sounds meaner. Runs a lot cooler, with a bit more low end punch.
