Thanks for the scan. The exhaust "unqiue design" suggests it's different from the PSE, is that correct? The numbers seem to suggest that the X51 would not be noticable by the "seat of the pants". 

 

Most probably it will be the same as the 911 Sport Classic exhaust, which from the video it sounds very good.

IMO the extra HP and the engine characteristics will be appreciated by people doing 250+km/h on the Autobahnen.

 

Actually NO. X51 on 997.2S models use unique exhaust with two double exhaust pipes.
 

So, there is the standard S exhaust, the PSE, the X51exhaust and the Sport Classic Exhaust?


PSE

 

X51

Pipes look the same as on XLS option.
