SYSTEM OVERVIEW
Our exhaust system uses larger piping compared to the factory exhaust system, yet weights 9% less than stock! We use 3" (76mm) OD piping, which then splits to a dual 2.5" (63.5) piping. The factory system uses 2.56" (65mm) piping, which reduces to 2.36” (60mm) before entering the muffler. It then splits and exits the muffler as a dual 2.36” (60mm) system, but reduces down to 2.17” (55mm) just after exiting! These reductions greatly diminishing the overall cross-sectional area of the system. The main APR tubing has a cross-sectional area up to 60% larger than stock! Finally, our system’s 4" (102mm) exhaust tips eclipse the factory 3.75" (95mm) tips, giving the rear of the vehicle a sportier look.
MUFFLER / RESONATOR
The rear muffler assembly is a dual Helmholtz resonator and muffler in one fully integrated package. The entire system is straight-through with a 3” (76mm) inlet splitting evenly to a dual 2.5” (63.5mm) setup for the vehicle’s dual tip configuration. Exhaust gasses pass through the muffler first, which is responsible for smoothing the exhaust note via perforated tubing that’s tightly wrapped with stainless steel and fiberglass material. Then unwanted frequencies are eliminated in the dual Helmholtz resonators. Exhaust gasses pass unrestricted through for maximum performance. The muffler / resonator setup has a beautiful brushed finish, and is tucked high in the exhaust tunnel, making it perfect for lowered vehicles.
BRACKETS
Our brackets ensure a strong and precise fit, every time. With our 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
We use T304 stainless steel tubing throughout. We brush and de-burr all pipes, use mandrel bending techniques to ensure the pipes keep a constant diameter throughout, and use TIG welding for a strong and attractive weld.
TIPS
Our polished slash-cut 4” (102mm) exhaust tips upgrade the rear of the vehicle dramatically. The motorsport-inspired tips tuck nicely into the factory valance, gently following the valance’s curves and demanding all the right attention in all the right places. We laser etch a small and discreet APR logo onto the top of each tip, and we use T304 stainless Torca AccuSeal clamps that bolt on with ease with hardware that rotates out of sight. Lastly, since the tips are removable, you can upgrade to any one of our optional tip designs at any time.
HANGER
We’ve added an extra bracket and associated rubber hanger to our system to make use of an unused factory mounting point. This ensures the system installs snugly in place, without an opportunity to move, or rotate, under prolonged use.
CLAMPS
Our system uses OEM-style low-profile slip clamps and T304 stainless-steel Torca AccuSeal clamps for the exhaust tips. 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. The clamps make for easy swapping of the exhaust tips, and slide out of the way to make adding or components. 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 pipe, 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
We’ve designed our system to be 100% bolt-on. There’s no cutting, welding, or finagling to get the system to fit. It simply bolts on thanks to the included reducer.
