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 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" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle. System Overview Our exhaust system uses larger piping compared to the factory exhaust system, yet weights 5 lbs. less and 1 lb. less with the optional front muffler. We use 3" OD piping, which then splits to a dual 2.5" design. The factory system uses 2.56" piping, which reduces to 2.36" before splitting, greatly diminishing the overall diameter of the system. Finally, our system's 4" exhaust tips dwarf the factory 3.15" tips, giving the rear of the vehicle a sportier look. Fits 2015-2017 Volkswagen GTI
