On3 or MMR coolant crossover delete? Which one and why?

[04dreamcobra]

As the title states. I want to know which one you chose and why. I cant find much on either of them realy other thatn the typical "it cleaned up under my hood" answers. I want to get a better feel for build quality, fitment, and how they have done after being on a car for a while. Thanks in advance! And of course any pictures are appreciated.

I have the MMR and it is pretty good. Nice solid billet pieces. I did have some fitment issues with the EGR tube when I had the EGR. They say it can be bent but mine was pretty well heat tempered. I used hi temp silicone and modified the tube this way. You can also put a new EGR tube on and it will bend easier.

I chose the MMR because I wasn't aware On 3 made one, and Cobra Engineering didn't have any.

I think I have installed pics on their for sale ad.
