Expensive does not automatically mean better either. Everybody else is doing it also does not make a superior product.
I suppose there is only one way to find out. I will report what I find, good or bad.
I am not "cheaping out". I have found a possible alternative that is over $100 less. As I said before, a catch can isn't a complicated piece of equipment. I could probably fab one out of a soup can and steel wool.
I really don't understand the resistance to someone exploring a low cost answer. I never once announced that the BT or Moroso cans were a waste of money. I really don't know. If the $20 catch can is a failure the I will buy a BT or Moroso and post a review on this forum that the eBay cans are junk. It's not going to ruin my truck. It's not an eBay universal camshaft or something. Sheesh.
I will say I am a bit leery about BT's website telling me that no one else but them can make a catch can and I shouldn't consider any other product when other companies have been making successful catch cans for years. Catch cans aren't new technology. Turbo engines have been using them for years to keep their intercoolers from gumming up. I would sooner trust a company that invites customers to compare their product against the competition...
You know, just a bit leery
