Overview 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 170x112mm ovalized diamond black exhaust tips finish the system, adding a classy RS-inspired touch to the rear of the vehicle.
