My DD muffler was very quiet until all the ceramic packing material inside blew out. The insides of my CME tips looked like someone had stuffed chunks of dryer lint in there. The original muffler blew out w around 10K miles on it. I found another DD takeoff on Ebay for $30. Not 4K miles later it did the same thing. You'll be able to tell when the insides blow out as the car gets noticeably louder and a resonance drone at speed begins to show.

My personal opinion is that the DD is the best sounding system available for our cars. No rasp or drone. Nice smooth tone...if you can hear it. Super quiet.

Makes big power and tames loud exhaust. Hard to beat in that regard.

I used to have a Magnaflow muffler on my car, which is also a quiet system, then I put on the SLP D/D catback and it's noticably quieter than the magnaflow. Even with a cam, longtubes and no cats, it's very tame. It's almost as quiet as my g/f's bone stock SS.
