APR Cat-back Exhaust System MK7.5 Golf R - No Valves/Mufflers

 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 Helmholtz resonator reduces unwanted frequencies. 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 quad 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

Valveless System

For the more track minded enthusiasts where weight, sound and price point all are highly desired metrics, the APR Valveless system is available. In this configuration the axle back portion of the exhaust has the mufflers and valves removed. Weight drops considerably and the system becomes more aggressive. With the factory DP in place, the system is louder and more aggressive, but thanks to the center Helmholtz chamber, drone is reduced, giving a more pleasant, yet aggressive driving experience.

Component Details

Downpipe Compatibility

We’ve designed our system to be 100% bolt-on with the factory exhaust downpipe. 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 downpipe.

Cast Splitter

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 quad 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

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 downpipe you may have. The clamps make for easy swapping of the exhaust tips, and slide out of the way to make adding or removing a downpipe easy. 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 downpipe is a breeze. There’s no cutting, welding, or glaring compatibility issues, and there are no gaskets to replace.

Created In-House

Our exhaust systems are proudly designed, developed, assembled and quality controlled in-house at the APR 78,000 sq.ft performance campus in Opelika, Alabama.
