The double wall tips are the give away compared to stock. I love my Tubi exhaust, particularly for daily driving or road trips. Practically no drone, quiet when cruising, but sounds exotic when at full wail.
When I bought my M5, I also didn't know it had exhaust on it as the seller didn't say anything about it. It wasn't until he fired it up when I went to pick up the car that I got a surprise at the increased rumble over stock.
