Yes because I left the stock Xpipe resonator and I emptied the Spipe cats leaving it to pseudo-resonate. (+ something I did secretly)
This transformed the rasp quality into a hollowish howling sound, more like a V10 V12 kind of rasp. the diablos have as well this kind of hollow howling bassy sound.

The engine metallic shriek is amplified intensly with this setup and it feels like a traditional BMW ///M motorsport sound especially when the revs climb, it sounds like an F1 car passing by.

Sometimes downshifting 2nd and flooring it next to a wall helps me listen to the car and it sounds like a catless gallardo.

Shifting abruptly makes some minor backfire and a whole lot of crackling and popping and burbles.

Let me know if you need any other information and happy decatting, there is some serious power to be had when decatting.
