Torx exhaust spacer???
I was looking online this morning for some winter projects to take on. I came across the Torx racing exhaust spacer, and found it to be interesting. For the price, $99.00 it claims to do a lot (1-2mph, up to 150rpm). I started searching for people who have actually used it, and was unable to find anything. I already have a riva high flow exhaust, and a TDR water box installed on my 09 rxpx. Would this product benefit me? or is this not worth my 99 dollars? Thanks

IMO it makes too much extra under seat heat
works great on a dyno not a pwc

I have added it to my setup. But these plates are not for stock skis. You won't see much gain on a stock motor. You need to be turning high rpms. My ski should be turning 8400 on the weekend after adding a bigger nozzle and this plate might give me those extra few rpm

I haven't noticed any. Probably because I did prop and ecu at the se time

the theory is that the spacer allows a little more of a straight shot out of the chamber before it enters the exhaust manifold. Getting the hot exhaust charge a little farther out of the chamber should lower temps in the chamber and on the top of the piston reducing detonation and increasing longevity. Since it is not water jacketed it can act like a heat sink and transfer heat into the engine bay like Chris stated.
quote from the late, great Breon (RIP buddy)
"i build headders for race cars at my shop all the time ...the worst thing you can do is make an abrupt turn right out of the head...the LOG style manifold does exactly that....kills the velosity ...makes it basically run into a wall...and it goes out the path of least resistance...kinda like trying to run through a door that didnt open as fast as you thought it would.....the spacer just makes the turn a little farther away ...lets it get away from the head a little ...kinda gives it a running start....but still at the wall....the manifolds are horrible for performance."
I have a spacer on order to try out. I am not expecting much but they are inexpensive and I don't feel like I have anything to lose

im going to try one on mine! sitting here waiting to go!
what do people use for gaskets between the spacer header and head? high temp rvt silicone?
