APR CBK0040 - Catback Exhaust System - Jetta GLI (MK7)

Overview:

Our exhaust system uses larger piping compared to the factory exhaust system. We use 3" OD piping, which then splits to a dual 2.5" design. The factory system uses 2.5” piping, which reduces to 2” before splitting, greatly diminishing the overall diameter of the system. Finally, our system’s 4" exhaust tips dwarf the factory 3" tips, giving the rear of the vehicle a sportier look.

Mufflers:

The mufflers are responsible for tuning the exhaust note and do so without adding unnecessary restrictions to the system. Each unit features a straight-through perforated tube that’s tightly wrapped with stainless steel and fiberglass material. The mufflers have a beautiful brushed finish, and are tucked high in the exhaust tunnel, making them perfect for lowered vehicles.

Helmholtz Resonator:

The front resonator is responsible for eliminating unwanted sound frequencies from the cabin. This is done without introducing added restrictions to the system. Using Helmholtz technology, sound waves bounce through the chamber and back into the exhaust stream, eliminating the undesirable frequencies to make the exhaust note more pleasing. During cruise the system remains calm.

Axle Back Components:

We cast the axle-back splitter to maximize the system’s performance by keeping exhaust velocity high and back pressure low. This is accomplished by gradually splitting the system from a single 3” pipe to dual 2.5” pipes. The organically shaped casting allows us to make this transition gradually as to not disturb the flow of gasses. Furthermore, as this component is visible from the rear of the vehicle, we made sure form matched function with a beautiful surface finish, TIG welding, unique bracketry and brushed, mandrel bent tubing.

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 argon-back purged TIG welding for a strong and attractive weld.

Tips:

Our polished slash-cut 4” 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.

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 for use with the factory midpipe. Use our optional link pipe for use with a 3" midpipe.
