Enjoying your work and vision....fun to personalize 911's IMO.
Did you notice any change in torque with the muffler change? Is the sweet spot higher or lower in the rpm range.....in my short 911 experience I've found the torque to be easily influenced by muffler tuning and lots of the aftermarkets (M&K in my case) reduce mid range grunt to a higher rpm...fine if you are always running at high rpm but not so traffic friendly.
