    Riva waterbox for 300 ?

    I Currently have Riva stage 2. In planning on ordering drop in sc wheel and injectors. Was wondering if anyone has feedback on Riva waterbox. Figured was good time to do at same time as wheel but any performance gains seen? If it's just louder I rather not. I gutted my stock and it's noisy and have friend that wants to trade for stock.

    I just switched to straight through exh no water box on XPL 4tec.. noticable better throttle response. Obnoxious loud. Seems the engine off iddle was struggling to push out water with WB . I always wanted to try a Jetworks flow valve to cap water flow at idle only.

    Personally I'd run a gutted stock box with thru hull and call it a day, unless you plan on running a header or straight thru exhaust like on his xpl 4 tec, there's minimal if any performance gains, just sound that adds to your butt dyno

    I care mostly about acceleration and mid range. I do have Riva thru hull
