Had FI in my H, and am going to the be the first owner to have FI in the Perf (under work now).

IT IS THE BEST EXHAUST OUT THERE. Full stop.

Yes, mine was / is valvetronic and can go from sounding like an ordinary Lambo to a screaming beast with the push of a button. Amazing.

And best of all, my better half calls the car "one nasty beotch" and she loves it more than I do.

If you don't have FI, you should.
