Vorsteiner exhaust system.
 

Hi guys..Looking to upgrade my exhaust system. narrowed the choices to either Dinan or Vorsteiner. Know that Akra is the best: cannot get myself to pay 6K for exhaust though...

Anyways I cannot find much in terms of user experience with the Vorsteiner system online. Lots of positive reviews on Dinan. Here is the system:

BMW X Series E70 X5 M Sport Exhaust System | Vorsteiner

The youtube video:

Vorsteiner Stainless Steel Sport Exhaust for the X5M/X6M - YouTube

Was wondering if anyone has any input. On video it sounds awesome. I read a lot about Meghan exhaust. Has good reviews. The problem is that it has to be welded on. I was looking for something that would clamp on so that I can swap it out if I were to sell the truck...

Thanks for any input.

What exhaust did you go with? I am considering Vorsteiner as well.
