Interesting find…

Congrats. Looks diff than my model but great find because they're highly sought after.

It certainly does sound great and looks subtle....

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.
