Hey Guys,
So sorry for the lack of updates here but I wanted to let everyone know that the issue was eventually resolved...almost 10 days after the original install. After a few back and forths, Infiniti and Ark worked together to figure out that there was a part (pipe) shipped with an incorrect label perhaps and the after-market folks at the dealer missed it and installed as labelled but after turning it the other way, it fit well enough.
Pretty low quality video here that does not really show the difference between the stock and Ark but there is certainly one at start-up and while driving, minimal drone. I could use it a little louder but everyone says there is a break-in. However, if it remains like this, I have no regrets. Finally closer to what this car should sound like...
