Is made by a forum Vendor Mighty Mouse Solution's.

The gunk coming out your exhaust comes from your crankcase oil combustion by product is drawn thought the PCV valve under the supercharger.

Through your blower this is where the oil under the lid shows.
But further inspection shows this stuff is drawn through your intercoolers
past your valves and in the engine. Remaining unburned gunk and byproduct is pushed through your exhaust out your tailpipes.

The MMS solution is a valve replacing the stock PVC with one that vents to the front and outward routed to the catch can. Then the catch can draws
fresh filtered air sucking and trapping all the gunk. Using the engine as the vacuum source. Genius IMO! I worked with Catch cans before not thinking much of them but this one is one well designed and placed system the real fix! Best 340.00 you can spend on the Z06.
IMO!

I thought that GM told us Catch Cans would void warranties

Yup

how dare you make your engine run cleaner

Time your warranty is up you would have possible issues starting from the oiling etc and the engine is certainly is better off with this mod.

plus clean exhaust tips.

good thing MM catch can is completely reversible if you got one. just need spare coolant hose

I hate the fact that I have to wipe down my exhaust pipe tips at least twice a week to keep it looking clean.

Not trying to start an argument, but I thought I have read numerous posts here & maybe a Tadge comment, that the residue on the outboard tips is from an overly rich mix the car is sorta burdened with.

I would say correct that can be a factor too on the stock car exhaust.
But MMS fixes the other issues as well as helping the exhaust tip issue.

Why are we bringing this topic up again?

madrob2020

Maybe he gets residuals?

One could ask why chime in?

I pull my supercharger cover and wipe out the oil every 2500 miles.it only takes about 20 minutes.yea it sucks,but warranty is still good.

No way that a catch can keeps the exhaust tips clean. I had a catch can on my Camaro ZL1 and the tips were no cleaner than before it was added. I do believe they work in catching oil vapor but no chance it would do anything to keep those tips cleaner. Maybe a .000001% difference if that.

That does little good the oil comes right back and passes though your intercooler. I had had my lid off and cleaned it as well a few times like you and found my
intercooler was still full of gunk and oil when I flipped my blower.
The vacuum sucks it right on in the engine.

I found the same thing the catch can was crappy till I tried this one.
NOT just a catch can but it IS catch can system with it own valve replacing the PCV below the blower catching crap straight from the crank case!
It is a much better set up and I'm sure it will stop the mess coming out the exhaust.

I'm only a few hundred miles into Z ownership so I'm glad to learn this. Did notice much dirtier tips than my C6.

I have MM catch can and my exhaust tips still get black after a few miles.......

fleming23

Your argument, and direct experience, is futile. This is the end all be all. He will be ordering 3 more soon.

That was sarcasm, btw (internet and all...) I have the MM can as well, any my exhaust is just as black as before, because the oil isn't what is turning the exhaust black, as was explained before, and ignored by the OP.

I think it's more about "We spent about $30,000,000 on complex fluid dynamic modelling simulations on the intake path to perfect it and you've now hooked a rubber hose and can up to it" so we won't warranty it anymore because it's no longer our design.

I'm highly dubious that the stuff the collects on exhaust tips has anything to do with catch cans, but not eager enough to bite at that one!
