APR Axleback Exhaust Conversions for the S3 Sedan
APR Catback for the S3 Sportback| 03/19/2020
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 brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions, while our Helmholtz resonator reduces unwanted frequencies. 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 quad 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. Our cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation. Finally, removable 4″ polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.

APR License Plates and Frames| 06/15/2021
APR license plate frames and vanity plates are the perfect addition for any APR tuned vehicle! They are made from sturdy and rust-resistant T304 stainless steel. They are thick enough such they won't flop around like throw-away handouts you find in a typical swag-bag at car shows. They feature a fade and scratch resistant black powder coated finish with laser etching for the APR logo. Anti-vibration backside plate tabs keep it firmly in place. Four slotted install holes give you the perfect fitment with a solid connection to the car. The nice hardware hiders give it a clean finish too, hiding your unsightly plate screws. Fitment is universal. Some have said this product will increase the value of the vehicle, while others have made horsepower gains, but we can't comment on either.
