Suggestion
If you want to go further changing the existing headers to SSI's and adding a 2 in/ 1 out (or 2 out but you may risk suffering annoying drone at highway speeds) will cost in the 4 or 5 grand area.

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 looking for recommendations to upgrade 911 SC sports muffler. What is the best sounding sports muffler? Wanting a nice racing sound but not ridiculously loud.
paul
Took my car in for a recent annual service to Autohaus Hamilton, and my exhaust needed to be replaced. They supplied and fitted a Dansk Sport unit. It's a little throatier than stock and seems to open up more when you put your foot down. The tip sticks out a little further than stock and seems to be larger too. Preferred the stock look but I guess I'll get used to it.
I have had the same criteria satisfied on two 911's now. Sporty, light but not too loud or with a drone on the h'way. I bought one of the SS Monty Mufflers. He has been making Porsche mufflers for decades - in Australia and sold worldwide. Great product.
Had a Monty on three different cars now. Great sound and fantastic quality. I bought a spare one recently just in case he retired and they stopped making them.
The reason I removed the Monty was due to drone at cruising speed, I don't know if there are different versions but mine had a huge outlet (3-4" maybe) and sounded literally like a thumping 350 chev motor (combined with the SSI's). Everyone could hear you coming (my poor neighbors
), I tried double layers of sound deadener behind the seats as it was a wicked sound but it didn't do enough.
The Dansk still gives a nice note at idle and under full throttle, would never look back.
Paul,
Just be aware that you can get Dansk and M&K in various noise levels
To play it safe with regard drone, most people seem to recommend single outlet
Dansk, M&K or Monty, I don't think you can go wrong.
I've put an IPE system on my C4S with the hi-flow cats and the valvetronic system. I really like it. I usually run it around in sport mode, and its no issue on the highway, however if you run it with tthe valves closed its really good with no drone.
Hi there, I’m also looking to upgrade my 82SC rear exhaust. It’s 1 in and 1 out by the looks. I love the sound of the M & k system from my brief online listening. Does this simply bolt on after removing the existing system? In other words no tuning or other adjustments??
the end goal is a better breathing and slightly better sounding car. Extra power isn’t the objective.
My Porsche mechanic seems to think there is more too it and it may have a knock on effect in other areas.
Suggest you have a closer look and maybe take a photo of what's on it now. This may save some time and confusion. There tends to be two levels of exhaust modifications:
If you are just after a change in sound, changing the rear muffler alone may be enough for you. Cost would be around $1000
If you want to go further changing the existing headers to SSI's and adding a 2 in/ 1 out (or 2 out but you may risk suffering annoying drone at highway speeds) will cost in the 4 or 5 grand area.
These changes will not result in difficulties with your CIS. Maybe an adjustment to the idle mixture.
Checkout what is there now and post a photo is my first suggestion.
