That's not a bad deal still. So it's their newest version with the GESi 50032 cats? And it's throwing a CEL? Could be due to the leak somehow. I'd get that fixed first and then see. Otherwise reach out to aFe.
Somebody posted a thread here a couple months back that seems to have since been deleted? But they came across people on other forums wrapping their exhausts and eliminating all rasp. I found a long thread on an Audi forum, where someone got the idea from an Infiniti forum (love the internet). It makes sense, and I'm confident it'll drastically reduce it on our setup.
