APR Catback-System Volkswagen Golf GTI MK8

The exhaust system uses larger pipes compared to the series and weighs 9% less. 3" (76mm) pipes are used, which are divided into a dual 2.5" (63.5mm) pipe system.

The stock system uses 2.56" (65mm) pipes, which reduce to 2.36" (60mm) before entering the muffler. The exhaust gases split up and leave the silencer through a dual 2.36" (60mm) system, which is immediately reduced to 2.17" (55mm). This reduction in size significantly reduces the overall cross section of the system. The APR mainpipe has a cross section that is up to 60% larger than the original. The whole thing is rounded off by 4" (102mm) tailpipe trims that give the rear of the vehicle a sporty look.
The rear silencer is a double Helmholtz resonator and silencer in one.

The entire system is a straight-through system with a 3-inch (76mm) intake that splits evenly into a 2.5-inch (63.5mm) dual exhaust system. The exhaust gases first pass through the silencer, which is responsible for smoothing the exhaust note. The perforated pipes were tightly wrapped with stainless steel and fiberglass material. Undesirable frequencies are then eliminated in the two Helmholtz resonators. The exhaust gases flow through unhindered and ensure maximum performance. The silencer has a beautiful brushed finish and is hidden high in the exhaust tunnel. The system is also suitable for lowered vehicles.
