One month ago I finally purchased my dream 82 911sc Slant Nose,now that I've put a few hundred miles on her, she seems to be getting louder and louder every time i drive her. I've had other muscle cars with similar extra wide tires that were not nearly as noisy. I've never owned or rode in an older Porsche before so i don't have a baseline to compare tol, however at 60 mph it exceeds 90 decibels.
What are normal sound levels, should i be concerned that something is worn out like a bearing or transmission, is there anything i can do or check before i open nearly empty wallet?
Thank you in advance for any suggestions
