I just bought a generic JDM catch can off ebay which doesn't appear to have any baffling inside of it. I want to use something for baffling, and I've heard that SS pot scrubbers or a loofah will work. But mine only has a small hole allowing access to the inside of the can so I'm wondering if the best thing to do is to buy some pot scrubbers or SS mesh or whatever and insert it into the small hole. I'm just wondering if having a medium sitting loosely in the can will work or if it needs to be stabilized somehow. Any help is appreciated!

 

I'd send it back and buy the generic can that you can fully open.

 

For ones that can open, u think using an oil filter would work? Ve a good idea I think. Just buy cheapest one and put it in the catch can

 

Ok so lets say I did have one that opens up. How would you do the baffling on it?
