Alright here are some videos. Cold start and kept it going until it went down to normal idle. Also tried to get some driving clips with windows open. I am just using my Iphone 15 pro, I don't have any external mics so not sure how great it is. My stock exhaust had definitely gotten louder over time and it's interesting because I feel that the sound off shifts is not any louder than the stock exhaust at WOT. It sounds more mellow and not as farty. Low speed is definitely louder than stock. I didn't mind the stock exhaust at WOT but the sound is too high pitched anywhere else. This really deepens the sound.
