To me it sounds too loud, I kinda regret I did this. It was so quiet before my non diesel friends went "Wow!" Now the noise inside bothers me as I drive and i feel redneck, this is MB not a truck. Two reasons I did this:

- I loved my SEC sound with straight pipe, but it was way different car
- from reading posts here I thought the dual resonator is clogged witch huge chunks of soot, turned out it was clean and free flowing

Well, it's ok for now, maybe I'll just play with it and put Ferrari muffler when I find one cheap
