Who makes this 18+ Diffuser cover? Cervinis?

I dont remember it touching during install but I will have to double check. My tips have always been uneven, but at least there evenly uneven.

Do you have a clamped H or X pipe? The clamps need to be retorqued after the install or they'll let the tailpipes rotate causing the tip droop.

That's probably it. I had the dealer install a fp x pipe when they did the supercharger. I just tried looking through old photos but I can't find one of the tips before I had it installed.
