{"type":"firestarter.listing","listing":{"id":"lst_z_orx7Mt","product_name":"APR MK7 GTI Catback Exhaust System","category":"Exhaust","description":"The APR Catback Exhaust System personalizes your vehicle’s looks, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through satin-finished mufflers are configurable to your desire, smoothing the exhaust note to a deep growl, without adding restrictions, rasp or drone. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. A cast 3” to dual 2.5” rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system, while looking tidy from under the rear bumper. Finally, removable 4\" satin-finished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.
