Had ghack done for $40 on a set of cans i bought for a $125 from a brother here. Total of $165. Best value for buck mod. Only thing is it seems that sound gets quieter after a few months...or i am just getting used to it.

 

Gundo,
Thanks for stopping by and the original idea.
Slicky,
You get kind of used to it but it still sounds great.

Outside of the Gundo (I have Darrins pieces) a new steering wheel made the biggest difference for my 997 experience

 

For some reason, even though I have a 997.2, I prefer the 997.1 steering wheel
