Super quiet at low rpms starts to resonate towards 2.5~3k.

Overall the sound is AMAZING!!! I have a 2.0T 07 Saab and sounds like a mean V6. Only downfall I saw was one magnaflow was polished and welds as well and other magnaflow wasn't polished on the welds, but I delt with that and still installed them both with 3inch piping. Autoanything was very fast in shipping it, however, not really reasonable with returning it because it was the wrong size inlet. So I had to use a reducer which isn't a big deal.

I have a lb7 duramax with a 4 to 5 inch straight pipe. It was ungodly loud especially on the interstate. This muffler doesn't make to much difference at low rpm (which it still quiets it down a bit) but it makes a world of difference once you give it throttle. Especially at 2k rpm when it starts to drone out. The truck still sounds awesome but not nearly as loud! It was exactly what I wanted!!
