So now you twist my point around like you did coSPEED.
If you cannot see that the pics LMR posted of the two hoses routed to the chin and venting to atmosphere are creating 2 draft tubes then there is not much point in further discussion here.
You like the LMR catch can and no discussion of its strengths or weakness by others will change your mind. Ok. Enjoy. I like that there are other vendors and products designed to work correctly on a street driven car.
Oh, and more frequent oil changes does not alleviate the problems with a vented to atmosphere system. The acid vapors and other combustion products stay in the engine and not swept out. Long term this leads to very dirty internals and other related problems. We can see this is of no concern to you. Ok, thats fine but it is to others, including GM and me.

Pretty soon it will turn in to "your wrong" and the coming discredits and smoke and mirrors, so stop (even though you won the argument ) with
the common sense stuff your in a no win conversation filled with pot holes and personal attacks and discredit no matter how right what you are saying.

Texas law prohibits any person from selling, offering for sale, leasing, or offering to lease any vehicle not equipped with all emission control systems or devices in good operable condition. Violators are subject to penalties under the Texas Clean Air Act of up to $25,000 per violation. Buyers are advised to have the vehicle checked for all required emission control devices prior to purchasing a new or used vehicle.
A vehicle may not be legally sold if its original engine has been replaced with another certified engine but without the related emission control components. Tampering includes the failure to install the emission controls associated with an engine configuration.
Mightmouse stays in closed loop unless there are pressures that build up that cannot be rerouted back into the engine, then it has a pressure relief.. I like that a lot. Most of our cars are not compliant after we modify, ie tune them. Just certain states are lenient and some are not. If I were boosted, the LMR/Lashway can is a great way to go, Mightymouse is great too, I currently run a UPR setup with the additional intake fitting. It is personal choice and what one feels comfortable with. Try selling more than one vendors cans and see your sales triple. Knocking others while boasting about the one you sell can only do you harm.

I agree!!!
Bashing another MFG on one item can also hurt your sales of all your other products. I just scratch my head when a Vendor bashes other Vendor/MFG products over and over with almost Manic Zeal....
It would seem a positive approach on why and how my products work better would be the ticket to higher sales and business success.

If it vents to the atmosphere period----it is not legal.... That is very easy to see when you open the hood. If you are good with that then fine. I run cans on all of my vehicles but one thing is different with the Corvette. The fan boys of the cars are more intense. Good God Man---it is still a Chevy!!!

Mighty Mouse has won several lsx shootouts hence the jackets 
I've been working on a catchcan setup in my shop in and off for a few weeks. I like the LMR/Lashway design which basically vents both valvecover sand the valley (3 connections, dirty side) then they use 2 vent lines (baffled from the 3 dirty side connections, which traps oil in the bottom of the box)
Instead of venting the 2 lines to the atmosphere I was planning on running 1 line to the centrifugal blower pre impeller (check valve required in line) the other line to the PCV port on the intake behind the TB (check valve here as well)
This would make the system closed I believe and relief pressure in all conditions, not just in boost.
Thoughts?

In case anyone is wondering, I called LMR and you can update your breather if it is one of the original releases to the new revision for $200.00. It requires you to send them your breather, and then they will weld the necessary adapters on for the hose rerouting and send it back to you will all new hoses.

On the can where there is currently the two filters, they are welding on two new special threaded bungs. They are including the two long lines that run to the front of the car. They are also giving you new lines that for the rest of the kit. I'll know for sure after I get my kit back (sending it out tomorrow). It does take time for them to weld on the new bungs and there is costs involved with the parts and lines in the revision. Now if you are asking why the markup is $450 when the revision is only $200, then I'm not sure. I am sure there is a reason though. Possible recoup on the R&D for the revision.

That's what I am thinking also. I'm sorry that just is not fair for the customers to pay that increase. You bought one before for $649, then spend $200 for the revision. That's $849, but they are selling for $1099 in black. So how I just don't get it. Before black coated was $50, now it's $100. Guess they had to revision the paint also.

Sycraft is correct on his answer.
But on those defeating all evacuation I have a few questions:
Does this conversion move to open hoses to allow in sand/dirt/water with no filters attached? I have gone into great detail on the negatives to an open draft system, but not a single person can explain how they think this wont harm their engine. Still waiting for factual explanation. Look back, I provided tons of research material for any that want to explore this. If you are aware of what happens to your engine when you defeat evacuation and allow unfiltered air in to your engine and still wish to run it this way that is your prerogative, but people need to understand the ramifications as these engines are not cheap!

you can route the hoses wherever and however you want if you choose to use them, personally i just use the open filters. that means you can route them in a way that is not parallel to the road in the first place.
second, the system is not a simple open tube hanging from the valve cover, it is a baffled system with constant crankcase pressure pushing against it, especially if you are boosted, which is what this can is meant for anyways.
so if you can, please support your statements, otherwise it does not lend to your credibility to make statements that are basically baseless.

Having gone through a number of catch cans on my C6 before finding one that actually worked, I will say that the buyer needs to be careful in distinguishing bling from actual performance. Most catch cans out there are beautiful looking, but don't actually work very well and are not as carefully researched as they should be. And it's not just about the can - it's about how the system is plumbed and how the check valves are configured. The can is the most expensive part, but it is basically little more than a container and is the least useful part of the system.
I have no dog in this fight, but I would suggest buyers pay attention to what coSpeed has posted on how a PCV system needs to work and do your research on which configurations will actually be effective. Again, it is all in the plumbing. The catch can itself is just a fancy box with baffles, and it could just as well be made of PVC plastic and do the job just as well.
