    Too loud Riva air intake & free flow

    To much loud and noise with less that a mile gain (hot weather) I decided to remove it and came back to stock arrangement…it’s only though what will be better gain in speed that the Riva performance air intake & free flow??

    I just installed the RIVA Box... actually I like it, but I always wear a helmet so the noise doesn't really bother me

    Again, note that the straight pipe is significantly louder than the RIVA Box

    My suggestion - if you race, go straight pipe

    no top speed gain with the air intake, only acceleration.

    top speed gain with the exhaust mod will depend on ski. do both.

    Did you gain RPM's with the air intake? I'm right at 7800 with the timing mod and see that most of the fast ski's are pulling 8200ish

    300 RPM is a lot of gain, I am still thinking you have a pump issue or something, 300 RPMs should be close to 2 mph gain..............

    I just had to chime in...
    I was playing with the idea of changing my box I decided no.. and then in the same breath i asked rudy to install it... yes it is noisy specialially idleing around the harbor... if you get on it - it's not too bad.. but yes it is a darnsite louder than stock.. I have not been to to many lakes or anything like that- but i'm sure that folks trying to sleep on the water in their houseboats or crusiers would not be too happy.
    I was beside this guy on a Sea Doo the other day... i could hardly tell his was on!
    I'll tell you this much.. if i ever decided to do the TN 600 it would not be fun for everybody.
    Good luck... mine is staying in.. loud or not.
