Those leak at all? Do they have a gasket on the top opening part?I know its less than ideal to mount both catch cans on this side...above the hottest part of the engine bay at that, but this is how I am rolling for the next two weeks. I've ran this setup for a few months. It's worked fairly well despite the long hoses and heat, but I need new hardware to delete the clear hoses on the can. They leak a little bit.
