    Cool through hull exhaust

    G'day guys ,
    skip here from australia and a newbie to this forum and seadoo rxps . I have recently bought a stock 04 rxp and intend to race it in my club races . I just ordered umi steering , sponsons to improve the handling and from I have read in the threads on this site I better get those pro opas block offs .
    Firstly I have to check with my club to ensure I can race my boat with the mods I want to do ( mainly through hull exhaust , due to noise level ) does anyone have a db reading of the riva through hull exhaust with stage 2 sc impeller ,ic ?
    IT would help me out to no end if I had the imfo. to take to the club meeting . We are having problems with local authorities getting permits near residential areas making it diffcult to organise races .
    thanks in advance skip

    most music or stereo stores will have DB meters under $100 US dollars..

    thanks for diy your suggestion rapidacceleration but the problem is i dont have a through exhaust yet . I am trying to find out if it would pass local authorities maximum levels before I commit to purchase a kit .
