Your car looks great too! Our cars look similar now minus the wheels being different, as I finally got the 3m window tint done. What interior did you go with?
Hi

I went to a muffler shop today. They lifted the car and looked at the system. They told me that by removing the resonators, the car "MAY" lose some back pressure and feel a little lag when car takes off, but may feel a little faster once the car is moving. Did you feel that?
Also, I compare your video sound to several stock M550 exhaust video, I really couldn't tell a difference (maybe because how the sound was recorded, the place, distance, etc). So I want to ask you, can you tell a difference? good difference? Please let me know. Thank you in advance.
