At idle:
Cruising:
This sound seems to emanate from the engine bay (2018 Mustang GT), but I can't tell. It first occurred on the very first start up after the installation of a set of Texas Speed headers. Confirmed this afternoon that, despite the next-to-zero clearance on the passenger side...

UPDATE 21 Feb 19: Full disclosure for those considering this system. When we cleaned it up a bit, we discovered some minor blemishes on the tips--nothing run over 1K miles remains...
My stock system (still on the car of course) has less than 5K miles. As the title indicates, I'm looking for a Borla ATAK system (part # 140684). Don't mind parting with some cash to make the deal happen. I will also pay shipping of both systems w/in the US if that proves necessary.
