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.
Muffler
The muffler is responsible for tuning the exhaust note and do so without adding unnecessary restrictions to the system. This system features straight-through perforated tube that’s tightly wrapped with stainless steel and fiberglass material. The muffler has a beautiful brushed finish, and is tucked high in the exhaust tunnel, making it perfect for lowered vehicles.
EXHAUST VALVES
APRs 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 factory 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 APRs extreme torture testing. All necessary hardware is welded into place and is designed to combat heat and vibration for years to come.
BRACKETS
APR brackets ensure a strong and precise fit, every time. With this design, you’ll never need to worry about the brackets sagging and losing their shape over time, or the post slipping out of the hangers. The brackets are rigid, exact in their position, fit snugly in place and are made to stand the test of time.
TUBING AND WELDS
APR uses T304 stainless steel tubing throughout. APR brushes and de-burrs all tubes, and uses mandrel bending techniques to ensure the tubes keep a constant diameter throughout, and are TIG welded for a strong and attractive weld.
CLAMPS
APRs system uses factory-style low-profile slip clamps. APRs 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.
COMPATIBILITY
APR has designed this system to be 100% bolt-on. There’s no cutting, welding, or finagling to get the system to fit. It simply bolts on for use with the factory midpipe
