Full Modular Catback Exhaust

Absolutely transformed the car. The S58 already has a mean side to it, but the IRL system unlocks a sound that's borderline unfair — deep, textured, and aggressive without tipping into obnoxious drone on the highway. Cold starts have a real snap to them now, and the mid-range growl under load is exactly the kind of theater you want from a manual M3.

Shipping was good however some parts were poking out the box and it actuall ended up damaging a bit of my back seats due to that.
