headers versus bypass exhaust
Thinking about doing an exhaust bypass or header change on my 991.2 GT3. So far Dundon seems to be in the running for a full system but still trying to figure out whether a center bypass is good enough. HP addition is not as important. More important is the sound. Anyone live in the South Bay in Los Angeles who is happy with their exhaust sound that I could meet up with to hear the difference?

What are you looking to do? What are you trying to choose between? Doing a center bypass versus headers? As in, one or the other?
I'd think that anytime you can bypass one of the mufflers - that will get you more sound than headers.

I got a huge increase in noise level with I installed cat-less headers. 90 db failed the sound check
Others told me the same happened to them...
