Definitive Catch Can thread
Most of the black soot on the bottom of the outer two pipes is a result of condensation in the exhaust tubing. Engine exhaust contains water vapor and when the car starts, the exhaust tubing is much cooler than that exhaust. The water vapor condenses and water runs the length and drips out the tail pipe. There is some amount of carbon soot in any exhaust system. Run the water through the carbon soot and it gets dirty. That leaves deposits on your tail pipes.
and clean. You have seen the full catch cans on these cars surely!
My 2014 had so much oiling it was coming out the exhaust pipes. The 2015 was getting it too but at much less extent. I just cleaned my pipes and drove and cranked several full tilt runs got gas drove some more and low and behold clean tips, Where before they would be on the way to black. So far it looks like the catch can is helping already.

EDIT Spoke much too soon on my results after seeing excessive oil drawing in the intake from the brake booster line from the can. I removed it and recleaned my intake. Put in all back together stock. After another 500 miles car is doing better than ever.
Car is just turning 10,000 miles.

Every car I have ever owned, including our current ones have black carbon inside the exhaust tips, not grey. Unburned hydrocarbons will deposit as black carbon soot.
A catch can will not stop all of the oil vapor but it will slow it down greatly.
Without the catch can you know some day the valves will need to be cleaned, with the can you might not have to or it might not be as bad.
I think it is worth it that is why I installed one on my car.

On warranty, the Magnuson/Moss act (in the US) makes it against Federal law to void a warranty from using/installing after market parts unless that installation directly resulted in the failure the warranty claim concerns. The burden of proof lie's with the manufacturer of the vehicle: http://www.mlmlaw.com/library/guides...s/undermag.htm
As there are a few systems that do NOT defeat/delete/or disable the functions of the PCV system the use cannot void your warranty. BUT, if you use one that defeats/deletes the functions of the PCV system, then it certainly would. An example is any system that would "vent to the atmosphere" or defeat the evacuation and flushing that that is critical to prevent engine damage or premature wear. That would be a direct cause of failure and justifiable.
Another example would be adding an aftermarket supercharger that raises cylinder pressures and power in an engine and drivetrain designed to handle a certain power level less than the mod will produce. Tunes come into this as well, but there are plenty of good tunes that do not add stress beyond the automakers stated power levels. And look at the LT4 compression ratio being 10:1 VS the LT1 being 11.5:1. Even though the LT1 will handle the power if tuned properly, it is falling into a legit reason to void a warranty.
So if you install a oil separating system that does NOT defeat or delete all the functions of the OEM PCV system (especially if it enhances and improves the functions) there is no legitimate/legal way a dealer can void your warranty. Now, that said this does not mean a "non mod friendly" dealer won't attempt to to intimidate a customer, but you would always have the law on your side. A vented or tank type that defeats evacuation would in all cases be a legitimate reason to void the warranty. That is why education is so critical when looking to prevent the issues caused by the oil and other contaminate ingestion. You really need to become educated (and not "mis-educated" by those that are not experts in these area's) on all involved.
Hope this helped. Ask any other questions in detail if anyone needs clarification. And also, California has it's own rules, the CARB certification they have implemented (Clean Air Research Board) that is required before anyone can install an aftermarket product for use on the street in that State, that is why most manufacturers will state "Not for street use in CA".

I don't own a new Z06, but I do own an old one.
I do have a new Z51, I did buy the RX single inlet catch can the clean side separator.
I am going to add the 2nd inlet even though they say I don't need it with the z51 without a SC.
It's a quality piece, a bit on the expensive side, but so was my car.

Let us know how it works!
So I don't get to into sales, here is the link to the thread I started for anyone wanting more info:
