I got it done yesterday and unfortunately it didn't sound like expected. It sounded good at idle and to about 2500 rpm, but after that it droned in the cabin pretty terribly. I'm not sure if it was the modification itself or if it's the shop that did it (leaning towards the latter). But my girlfriend is hating it cause she can't hear anything I say when I accelerate. I tried taking a video but unfortunately my phone doesn't pick up the droning.
I'll record how it sounds at start up and idle and try to get another one of in the cabin. But I've already got an appointment to switch back on Tuesday
