So I’m throwing this out there just for opinion.

Looking at the NHP style of muffler bypass for the 996, it offers significantly greater area and length of piping, routing the bypass pipes right where the factory muffler would be and allowing for factory tip installation. I wonder with the extra piping if it helps reduce drone and other unwanted noise.
My theory if I combine that with my 200 cell X pipe, it will very much sound cup car like. Has anyone run this setup, and is it actually tolerable vs the shorter bypass pipes? I remember a company After Hours Exhaust, they did something similar but with resonators.
