I was wondering which full 3" turboback has the least drone noise inside the cabin? I am currently looking at the AMS turboback with resonated test pipe.

Any suggestions? I'm in California so i need to keep as quiet and non-bling as possible.

 

Injen is quiet and comes out the bumper staight. No drone. Has a resonator and muffler necks a little. Had it on my car for 5 years now. Don't DD it anymore but when I did it was nice to not aggravate me on my daily commute
