    Riva free flow VS R&D Sound supression removal tube

    Looking to purchase a free flow and came across this tube from R&D.

    whats the difference between the two? One better then the other?
    Any different gains on either one?

    pretty much they're the same. you'll see loss in top end but a gain in bottom end. i personally choose the rive free flow blue tube over the R&D sound suppression removal because with the R&D one it will require you to cut your oem tubes (i believe). also there is a higher risk of water leaks. go wit the blue riva free flow tube and call it a day.

    just out of curiousity....why do you want a free flow? the main reason why people get it is due to detonation on highly modded skis. or because of the way it purrs

    if you dont want to lose top end then stick with the oem sound suppression.

    if your ski is gonna sound badass then you need to make sure you can back it up.
