I have a 3DR hood. The full carbon. It's about 1/3 the weight of stock. It does not have tubes on the inside but is designed not to take on water. There are no front air intake holes. I've ridden in the surf many times and not had a problem with water intake.
As for reinforcing a SXR. I really don't think it needs it.
Good luck on the project DJ
