Can you guess this muffler?

I can’t. I’ve had the car for almost a year. Don’t get me wrong, I love the sound. Not too loud and not too quiet and also no drone whatsoever. I couldn’t find any markings on it anywhere.
It’s a 1 in 1 out as well.
Thoughts?

GHL perhaps?

Looks like a Borla. One of my favorites back in the day.

Interesting choice for a 911? We usually reserved those for V8’s.

Are you referring to generic / universal "turbo" mufflers? (not to be confused with Porsche turbo) Like Magnaflows? If so, I do not believe Borla mufflers operated on the same principle...

Also, I believe there are quite a few folks running Magnaflows, or Flowmasters, on their custom air-cooled exhaust setups.

I’m referring to a chambered Borla muffler that my friends and I dreamed of affording for our classic chevys in the 90’s. I didn’t realize Borla made a “turbo” type of muffler for other setups.
