Product Description
APR Catback Exhaust for 8Y RS3
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 or rasp. 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. Dual 2.5" mandrel-bent exhaust paths provide an ultra-smooth path, steadily feeding exhaust gasses out of the quad exit 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 for variable sound levels. Finally, our quad exit exhaust tubes exit the system into the beautiful factory RS bumper integrated exhaust tips

SYSTEM OVERVIEW
The factory exhaust system starts life as a dual tube setup but then converges to a single tube before entering a suitcase style muffler. Our system uses dual 63.5mm piping with no mid mufflers or resonators, and continues all the way to our large sound absorption rear muffler. The cross sectional area of our dual setup is 26% larger than stock! There the system splits to a quad 63.5mm design. Internally the valved path is straight through with no muffling, while the unvalved path is perforated for sound level reduction. This exits the rear into the factory integrated exhaust tips.
