Although I have asked this question before, I want to present it again in a slightly different manner. First to digress, I've owned my CGTS for a few months and I am really enjoying it. With much assistance from the Planet 9 members, most of my questions and concerns have been answered. The only real complaint I have is with the "Drown" sound from the exhaust when on the highway when in 7th gear (PDK) in the 2,000-2,800 RPM range. It doesn't really matter if I'm in comfort or sport mode. Interesting enough, it seems to be louder after the car has been driven for at least 8-10 miles. When I posted this question before, there wasn't any real answer except one member wrote that this drone sound should disappear around the 15,000 mile range. My question is if I can change or modify the exhaust system to alleviate this sound without investing in an exhaust system that is loud to begin with. Also, has anyone addressed this problem with a Porsche dealership mechanic? If so, did they offer any remedies? Thank you again for your knowledge and expertise! I truly appreciate it!
