Just realized magnaflow has an audio clip. Between that and your videos, seems it’s about as loud as stock but deeper. Has that been your experience?
Magnaflow's video:
Hey guys I thought I’d share what I did to get MagSafe charging in the console in front of the shifter on my SR5 (no wireless charger equipped). Simply taped an Apple puck using a roll of foam tape, which is the Same removable tape used for 3M Command hooks
Just got a new SR5. I hear the same thing with and without AC on and seems to change under engine load and throttle input. Possibly the D4S system turning on and off the direct injection?
