    waterbox

    is there a way to mod an rxp to get a nicer/louder tone without removing the waterbox and exhaust? does taking the waterbox insulation off do anything as far as sound goes? who has taken out their resonator and is it easy?

    Jfizzle,
    It is very easy to get the resonator out, and a piece of straight aluminum pipe from a muffler shop to connect the ends works fine. It sounds A LOT better by doing this. IT Is definately the "poor mans" exhaust upgrade, and if you dont chop up the resonator you can always go back to stock if you dont like it.

    u need 2 loosen the vts and move it over so u can get the resonator box out so u dont haft 2 cut it up, i think the riva resontor pipe is about 30 couple of dollars

    i just pulled my resonator out and didnt have to cut it or remove vts. u simply take the throttle body off which is only 4 bolts and rotate it up out of the way. and then i wiggled the resonator out. takes a few minutes but its the easiest method ive seen.

    superduty, you're right... on an RXT the resonator pops out with a just a little twist. Same with the stock IC... it clears the gas tank without loosening the intake manifold.

    So there is some good in having a longer hull...
