I just got the Magnaflow 14851s installed in my car and they look great! I was really concerned that the tips would look way too big on the car, but after seeing them installed, I am very happy.
As suggested, the resonators are still on the car. My opinion is that the car is still very quiet. After about 2.5k-3k RPMs, you really can't hear the exhaust nearly as much as the intake. Inside the car, I can hear the exhaust until about 2.5k RPMs, but afterwards I can't even tell I have anything special on the car. The guys at the shop suggested that I leave the resonator on the car as well due to the real possibility of heavy resonance within cabin, which I really wanted to avoid.
Sorry for the poor quality and short videos. That's all I had time for...
