Riva water box and rear exhaust setup

[sdxjet]

I was wondering if anyone is running Riva's water box & rear exhaust setup on any of the 2012-2013 models. I'm looking to install it on my '13 RXT-X, but I'm concerned that the performance gains may not balance out the cost. I'm in the process of adding R&D Stage 3 which requires a free flow exhaust so I figured why not go all out with the box and rear exit if it is actually worth it? Thanks.

In my opinion no it isn't. The gains from a rear exit vs a free flow in the stock location are non existent plus now you have a hole in your hull to deal with.

Good point on the hole and thanks for the feedback. It's a $700 investment and with no return on performance I'm really leaning towards the free flow.

That the route I went. Only difference is a quieter idle compared to the rear exit. And of course the price is much more adorable.
