Took my car to the shop today only to learn that the system would restrict the exhaust flow. The piece itself was excellent (two professional opinions) but just to small at the end...about half and inch smaller diameter than the pipe coming from the engine. Also, the end would have to be removed and an elbow would have to be put in at the end (very tight angle) which would cause a restriction (Restricting the V12 is not a good thing to do). So...gave the exhaust to a friend...and will be on the lookout for an AMG one pop out sometime.

 

who was the manufacturer of yours?

 

Bought it online from a private manufacturer. Price was very good, part was excellent, so I bought it. Good part, wrong fit, what can you do?
