NEW PRODUCT! RIVA Sea-Doo Exhaust Race Plate

[Cagedup]

Ok I'll do it

So no one has any solid results from this? I can see where you may not see much difference on a bone stock motor. But I want to try one on my RXP 300. I can see with tune adjustments where this plate couldn't do anything but help. Especially has restrictive as the stock manifolds seem to be.

Well I guess I'll be the one post the results. Currently I am running 81mph with a HPT tune, rear intake and resonator delete. That's with the seat on and my big a$$ on it (210lbs). I will post results of this RIVA race plate in the coming weeks.

These have been used for years. I have an exhaust spacer on my RXT and gained around 100 RPM. The only thing new about this spacer is the EGT and O2 sensor ports.

What RXT do you have ? S3 or new hull ?

Neither I have a 2006 RXT that has some decent mods.

Very nice hull !

Yea I know they have been around awhile but I have yet to see a testimonial of, "I bolted this on and after tune adjustments and data logging I got 125 rpm and 1.5 mph". All I have heard to this point is hearsay.

I'm a facts and data kinda guy.

Whether the exhaust spacer adds a few rpm or not, the important fact is it is datalogging "tool", superior to drilling your exhaust manifold, if using a standalone ECU. I'm not sure Maptuner X supports EGT probes.

I contacted Riva and they said you can add EGT logging via some additional PLX module but I'm not touching that monstrosity. It has only 2 inputs anyway.

Would be much better if MaptunerX got firmware update to support logging of custom can-bus data.

I agree, and that module doesn't appear to be water proof or resistant. Hopefully, Riva will have a better mouse trap soon.

Picked one of these up solely for the ease of O2 sensor install. My 2016 rxt260 has a molded in water neck that is in the way where most people tap the exhaust manifold so I couldn't easily install the sensor there. Figured if I'm going to have to pull the manifold either way might as well make it easy and gain a couple rpm!

Did you use any gasket sealer or high temp RTV on any surfaces when re-assembling the manifold or new plate?

I did not. According to the instructions they just want you to make sure all the surfaces are clean and torqued properly. No additional gasket/RTV needed.

I used a very thin layer of high temp rtv on both sides of the spacer......for piece of mind. Is it necessary? Don't know, don't care as I wanted to ensure no exhaust leaks.
