APR Catback Exhaust System w/o valves/mufflers for MK7 Golf R
Die APR -Katzenabgas -Abgasanlage personalisiert das Aussehen, den Ton und die Leistung Ihres Fahrzeugs. Wunderschön handgefertigte T304-Stall-Stahlkomponenten schmücken das System mit atemberaubendem Tig-Ablagen. Unsere durchstürmte rostfreie Stahlrohrleitungen verleihen dem Auspuff einen aggressiven Knurren ohne Beschränkungen, während unser Helmholtz-Resonator unerwünschte Frequenzen reduziert. Starke hochwertige Bracketry- und OEM-Klemmen im Stil halten das System stetig an Ort und Stelle, wodurch die Installation oder das Entfernen von SNAP und Einrichtungen einfach und dennoch präzise gestaltet werden. Ein Guss 3 ”bis Quad 2,5-Zoll-Splitter erzeugt einen ultra-glatten Übergang, der stetig aus dem System herausgefügt und unter der hinteren Stoßstange unter der hinteren Stoßstange aussieht. Zuletzt abnehmbare 4 "polierte Schrägstrich-Abgas-Auspuffspitzen beenden das System und fügen dem hinteren Teil des Fahrzeugs einen noblen Motorsport hinzu.
Für die rennstreckenorientierten Enthusiasten, bei denen Gewicht, Klang und Preis alle hochbegehrte Kennzahlen sind, ist das APR Valveless-System die gewünschte Konfiguration. In dieser Konfiguration werden die Schalldämpfer und Ventile des Endschalldämpfers entfernt. Das Gewicht sinkt erheblich und das System wird aggressiver. Mit dem werkseitigen Downpipe bleibt das System lauter und aggressiver, aber dank der zentralen Helmholtz-Kammer wird der Dröhneffekt reduziert und sorgt für ein angenehmeres, aber dennoch aggressives Fahrerlebnis. Wenn jedoch auf die APR Race Downpipe aufgerüstet wird, verwandelt sich das System und wird unverblümt roh mit maximaler Aggressivität - ein wahrer Traum für Rennstrecken-Enthusiasten.

System Overview
Unser Auspuffsystem verwendet im Vergleich zum werkseitigen Auspuffsystem größere Rohre, wiegt jedoch gleich viel. Wir verwenden 3" Außendurchmesser-Rohre, die sich dann zu einem Vierfach-2,5"-Design aufteilen. Das werkseitige System verwendet 2,57"-Rohre vor dem Resonator und 2,78" danach. Schließlich überragen unsere 4"-Auspuffendrohre die werkseitigen ovalen Endrohre und verleihen dem Heck des Fahrzeugs ein sportlicheres Aussehen. Das untenstehende Diagramm zeigt das System mit hinteren Schalldämpfern und Ventilen, die optional entfernt werden können.
Mufflers and Resonators
Valved System:
The rear mufflers are responsible for reducing the exhaust note and do so without adding unnecessary restrictions to the system. Each unit features two straight-through perforated tubes that are tightly wrapped with stainless steel and fiberglass material. With the valves closed, the system is tamer, but once opened, the system sounds deep, throaty and aggressive! The mufflers have a beautiful brushed finish, and are tucked high in the exhaust tunnel, making them perfect for lowered vehicles and a treat to see when looking at the vehicle from the rear.
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, with the valves closed, the system remains calm.
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. However, when upgrading to the APR Race DP, the system transforms and becomes unapologetically raw with maximum aggression – A true track enthusiast’s dream.
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.
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.
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 DP 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 Race DP 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 DP, APR Race DP, or other Race DP is a breeze. There’s no cutting, welding, or glaring compatibility issues, and there are no gaskets to replace.
DP Compatibility
We’ve designed our system to be 100% bolt-on with the factory exhaust DP and APR Race DP. 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 DP, and link pipe for use with the APR Race DP.
