What is everyone's thought on doing this on a 2020 AR210? Is it even worth the trouble?

It is a spark arrestor to prevent a backfire from reaching the intake side of the manifold and coming into contact with the fresh air and fuel prior to the cylinders. See link below:What's the original purpose of the ribbon? Looks like some sort of screen/filter to keep out debris maybe. Any negatives or risks?
I am covered under the YES warranty for a couple years, so hesitant to do anything that could void the warranty either way.
Ah I do remember reading about that requirement in the boat safety course.It is a spark arrestor to prevent a backfire from reaching the intake side of the manifold and coming into contact with the fresh air and fuel prior to the cylinders. See link below:

Backfire flame arrestors have been required on motorboats with inboard engines since 1940. Learn more about what they do, as well as how to inspect one.www.boaterexam.com
Because on modern fuel injected engines the probability of this happening is very slim. That being said, some people (I will do this if I delete the ribbon this winter) replace the entire air box and filter when they do the ribbon delete. They replace the air box and filter with a USCG rated air filter that is designed to act as a spark arrestor. That way you get the great airflow without the added amount of minimal risk or being out of coast guard compliance.Ah I do remember reading about that requirement in the boat safety course.
Is there a reason many seem to have deemed this as non-essential? I am guessing this may have been debated in the past.
Gotcha... Yea I thought that requirement was just for carburetor engines. Either way, replacing the filter with the arrestor included sounds like a no brainier when removing the original, as long as it doesn't just move the bottleneck.Because on modern fuel injected engines the probability of this happening is very slim.
