Anyone dyno'ed the coupe midpipe modification?
 

The coupe midpipe has a good sound to it. Actually I am thinking about getting the 05-06 midpipe from a sedan for a smoother sound to it. Anyways has anyone dyno'ed this mod to see what kind of extra power is put down to the wheels?

I would imagine it would hardly be noticeable. Temperature/humitidy variances could account for the gain/loss of horsepower as much as a coupe mid pipe.
