Suggestion
If the car has spent time in areas where snow and ice are common and salt is used on the roads the exhaust system hardware (along with heat shield hardware) can rot and things can get loose and noisy.
Leading evidence: 'Use on the roads the exhaust system hardware (along' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use on the roads the exhaust system hardware (along' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi guys,
So everything I posted in my previous post has been solved. Now I notice that sometimes, for brief moments when I am at idle, there is a slight drone coming behind the left exhaust, or so it sounds to be from the exhaust. Anyone else have this? It is not always there, just for brief seconds, and goes away, then comes back in like a minute for like 4 seconds and goes away again. Any thing to worry about? Since I just purchased the car recently, I am not sure what noise is normal, and what is not.
If its coming from your exhaust pipes, don't worry about it. It could be a cat converter rattling or a heat shield.
All 911 motors are noisy, they produce a lot of mechanical noises compared to Honda/Toyota six cylinder motors. Don't sweat every noise. Go and listen to the air cooled 911, you would think that car is falling to pieces..but that is how they run.
Stop listening to noises, take a pill from my avatar.
It is probably exhaust system drone. If the car has spent time in areas where snow and ice are common and salt is used on the roads the exhaust system hardware (along with heat shield hardware) can rot and things can get loose and noisy.
Even if the car has not been exposed to snow/ice and salt just age can do it depending upon the climate conditions. 'course, there is always just plain old old age which can have something loose. (My Boxster lost some nuts on the studs that hold the stiffening panel to the rails under the engine. Don't know why. Just spotted some missing one day.)
However, you need to get an expert's opinion and that means let a tech give a listen.
Secondary Air Injection, SAI, cycling. SAI is injects air to heat and light the cats quicker at cold start. Also will cycle when needed to keep cats hot.
It can also sound like an angry vacuum cleaner when the bearings get older.
