I was looking into these at one point but decided I will (eventually) get the Fast Intentions catback (I already have the RHFC's paired with my IPL exhaust).
My concern would be, will they even fit?

Just checked underneath the car. There are two exhaust hangars holding up our Coupe's suitbox of a muffler. One hangar is to the OUTSIDE of the exhaust pipe to the outside of the car. The other hangar is back where the muffler meets the pipe coming from the resonator. So just from a hangar-perspective alone, the hangar shown won't fit but they can be easily added on. The key is the angle this exhaust meets with the back pipes. If this doesn't match, then all bets are off. The FI would be the best option to pursue.
Would be cool to hear this on our cars though. Love the look!
Looks like just a straight pipe with a resonator on the side
There is some science behind this design. Its a Helmholtz resonator that cancels out certain frequencies depending on the length of the resonator. The longer the resonator, the lower the frequency that is canceled out (i.e. drone). Pretty cool concept.

I learned about this on my 1993 300ZX. I bought a Magnaflow muffler that came with high praise. However the drone on this system was WAY TOO MUCH for my 56 year old ears. So i had the exhaust shop create me helmholtz resonators (which you can see in the picture). All it is is the long tubes that shoot off the exhaust tubing and was tucked under the car. It did help certain frequencies and i was focused on the 100-200hz sound, but it never got rid of all of it so I sold the system.
The other picture was the frequency spectrum from my phone that shows the high dBs coming from that frequency range.
