Yep. Dinan Black Diamond exhaust. Wonder what my warranty is on them? Looks like 2 years. I am almost certain now this is what is making my whining rattle under low RPMS now too... crapola. It starts happening around 10-15 minutes into driving, and that's about around the time the exhaust really gets "warmed up" I think. Gotta get back to Prestige BMW in Ramsey... at this point I'm almost tempted to put my stockers back on....
