    Going to agree with the previous review

    I am going to agree with the previous review, my RS 4 came with two inserts the quite insert and the spark arrestor insert for my 2020 CRF450X (which was nice BTW)
    The quite insert seems to take the sound to a nicer level but the spark arrestor one seems a little louder. I assume the extra cut out pieces in the quite insert make the difference.
    I am required to run the spark arrestor by law and for piece of mind.
    I have thought about cutting off the spark arrestor screen and welding it on the quite insert but if you guys have other options for the RS 4 to get it to 94DB with a spark arrestor also, I and others on the forums would be interested in them.
    As the saying goes “Less sound = more ground”

    We have tons of options that might work for your application. Please call into our customer service team 800-634-9166 as someone can help you sift through the options.

    Works good wish they would make it with the spark arrestor

    It reduced the sound to a nice level like the other exhaust I have but my other exhaust has a spark arrestor also.
    I wish they would integrate the spark arrestor onto this part as the spark arrestor one does nothing to reduce sound..

    We may have other spark arrestor options not listed for your application... What iis the year, make, and model of your bike?
