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

Installation Instructions

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.

Exhaust Valves

Our system features two valves that allow control of the volume of the system via the factory exhaust valve actuators. In doing so, the system can go from tame to aggressive instantly! Unlike pneumatic systems, and other common valves found in the market today, our system maintains identical OEM operation all the way down to the factory valve actuation angles. Furthermore, the system is fully compatible with exhaust remotes, allowing end users to manually open the system at the click of a button. We cast the valve housings out of T304 stainless-steel. Internally the system uses CNC-machined T303 components and brass bushings, which have stood up to our extreme torture testing. All necessary hardware is welded into place and is designed to combat heat and vibration for years to come.

Clamps

Our system uses OEM-style low-profile slip clamp. Our clamp selection allows the system to sit high in the exhaust tunnel, as is favored by lowered vehicles, with ultimate compatibility no matter what midpipe you may have. Each connection point is strategically placed to ensure the system has minimal opportunity to rotate during install or during years of heavy driving. Finally, because there are no flanges or swedges on the tube, fitting the system to the factory midpipe or others is a breeze. There’s no cutting, welding, or glaring compatibility issues, and there are no gaskets to replace.
