Description

The APR Catback Exhaust System customizes your vehicle's appearance, sound, and performance. It features handcrafted T304-stainless-steel components with TIG-welding throughout. The straight-through, brushed-finish mufflers produce a deep growl without restrictions, while a Helmholtz resonator reduces unwanted frequencies. High-quality bracketry and OEM-style clamps ensure steady, precise fitment. A cast 3" to quad 2.5" rear splitter smoothly guides exhaust gases. Cast valve housings allow the use of factory electronic valve actuators, maintaining OEM valve operation. Removable 4" polished slash-cut exhaust tips complete the system.
