[Stück]

I can't even begin to describe how simple the whole swap was. BMW even dimples the factory pipes where you're to cut and clamp the new units in place. Very slick. Getting everything lined up was easy. The complete install took about 30 minutes.

Sounds killer, nice burble/pop on overrun decel especially when colder. Great cosmetic improvement over the cheap looking factory tips too! No drone that I've noticed at freeway speeds, and has just the right amount of cabin intrusion with the added sound. With the stereo on at a moderate volume you can't hear anything different inside.

Outside it has a much improved aggressive note, actually being able to hear the turbo spool is wonderful.
