Looking to upgrade my 1973 911T 2.4L muffler sound are there any suggestions?

isnt there a sport muffler available ?

Modify your original muffler to twin outlet. Someone should have the drawing on how this is done. Very efficient but loud.
I did this years back, but I kept hitting my shins every time I did something in the engine compartment.

There are many versions from which to choose, but Scart would be my suggestion: https://scart.com/en/porsche/911-196...va-sound/73-51

Yes I did some research today and M&K makes one. Thanks for the suggestion.

Thank you my gut was telling me this could be an option I will keep digging. I was looking at this Scart video today and it was awesome.

I have had RarelyL8 headers with heat and M&K GT3 style twin center out muffler on my 911 with a Steve Wong chip for 10+ years and love the sound and performance: www.rarelyl8.com

M&K single in single/dual out.

You want dual-in/dual-out for the best performance and sound.

Yes but if you are in California, that's not gonna happen, have to retain cat no ?

factory is the best there is no "upgrade" only a down grade for a bunch of noise, and less power off the line and more power at the top end
