3is Custom Exhaust Recommendations

Personally in my opinion the car sounds like a freaking Camry with the resonators. Huge turnoff to an otherwise great vehicle. I did come over from a F32 335xi so maybe that's why it l love the sound. As my setup sounds a little European-ish imho. I went with 3inch all the way and 4inch tips. Haven't had any kind of emissions issues with the dealers or any lights/codes come up. And in fact many trusted sources have assured me deleting the secondary cats alone on this vehicle shouldn't cause emissions issues if done correctly.
What's the biggest difference between having resonators/ not having other than sound? We only deleted the resonators after having the full system built and it STILL had that mechanical sounding whine.
