Well it depends on whether or not you want the Spacer or ISO Thermall in the 5/16th or 1/2 or just eh mrev+ v2.
The mrev+ V2 with core exchange is 122, when he puts it on sale, but you have to give a core deposit of 244 which gets refunded once your core is recvd.

So with the iSO 5/16th Spacer the total cost would be $417 + Shipping.

The spacer actually does help, but only a little, because the flow of MREV V2 is already that much better than stock.
The truth of the matter is that once I put the spacer on, the ECU pulled timing to avoid knock. If you have access to something better than 91 octane then you will make better power from this mod because the ECU will not pull timing.

Just wondering...I'm detecting no knock on my MREV++ setup with a 5/16" spacer on my stock FX35. Only things extra are a K&N drop-in filter and a Z-tube.

a little OT: im afraid id be running a little lean with the MREV V2
i already have the spacer, a pop charger, and a catback and im getting some new cats soon.
does anyone have any thoughts on this...i plan to get an eManage ultimate but i dont want to until its absolutely necessary (i wanna get the most out of my mods by putting as many on before i have to tune)

Look at 6000 RPM. 10 lbft gain of torque at 6k rpm roughly. Since horsepower = torque x constant x RPM , that's why it makes so much peak HP.
Also notice that after 4k RPM, the AFR stayed the same as stock. That means this is not just making power by leaning out the already-rich top end.
Another thing:
Note how the 3 baseline pulls get progressively worse and worse by as much as about 6hp. The highest HP is the first and best baseline, the lowest HP is the third and worst baseline.
The dyno operator explained that this is typical and is essentially caused by heat soak.
The isothermal gasket helps significantly with heat soak so you can see, the 3 modded pulls are more consistent than the 3 baseline pulls.

I mention keeping stock exhaust because bigger exhaust does not necessarily mean better. Maintaining a high exhaust velocity is important (velocity decreases with increasing diameter). But you also don't want a lot of backpressure. So keeping a modest diameter but reducing restriction by replacing the stock cats could potentially help a lot. I am not 100% sure about what I am saying here, but this is what my engineering intuition tells me. I am not trying to bash aftermarket exhaust systems.
If I could get a tune for cheap (hoping for some cheap e-manage ultimates to show up) then this could make even more power and prevent knock better than simply adding higher octane gas.

Stock flows down to 2 inches
I made power switching from my Talon from 2" stock to 3" mandrel bent. Anything larger and I would have lost velocity. Like blowing through paper towel tube and blowing through a straw. You feel more air velocity through the straw. The straw is too small and the paper towel tube is too big so the trick is the happy medium. I have the Ti single tip MagnaFlow which is 3.5". I can feel plenty of velocity with my hand just behind the tip
