Anybody know anything about these? They are a single cat set-up (per side), as opposed to the stock dual cat set-up, with the flex joint and they supposedly flow better than stock. I can get a pair pretty cheap but I don't know whether or not they'd be an improvement or if I should go with one of the other high flow options. Any input is appreciated. And before someone says it, yes, I already tried multiple search variants without any results.
