Possible to make QUATTROPORTE S exhaust sound like GTS ?

[Zep]

From what I can work out, the major difference between a GT and QP back boxes is the length of the outlet pipes.

So you could just get some GTS boxes and extend the tips.

Don't the intake nostrils on the GTS provide some turbulence that gives the GTS that distinctive burble? Or am I just making shite up? I can't imagine how the airflow could retain the same turbulence by the time it gets to the other side of the engine, but there are lots of things that defy my imagination.

I think those are "resonant chambers" rather than nostrils (ie no hole). I am intrigues how these affect the sound. There are aftermarket ones you can buy which claim to do so.

They are, quiet as it’s kept, Holmholz resonators. They actually smooth out pulses from the inlet and make the noise smoother. Fun fact, Redbull used them in the exhaust of their F1 car in the blown floor era to improve aero stability.

Tried that. The ones I bought were completely different and did not fit. They were from an mc from memory.
