HJS ECE downpipe 3" VW Polo AW1 GTI 200hp 90811165 (HG90811165)

Downpipes play a key role in pulling power and performance. They are the “link” between the exhaust side of the turbocharger and the exhaust system. The catalytic converter developed by the HJS tuning experts has gone through every development stage. The significantly reduced exhaust back pressure of the HJS tuning catalytic converter not only lowers temperatures in the turbocharger but also gives a noticeably better engine response. Naturally, the improvement in power and torque can be clearly felt. In addition, the metal substrate used gives a more sonorous sound. The advantages at a glance: • 200-cell tuning stainless steel pre-catalytic converter • 100-cell motorsport stainless steel main catalytic converter • No registration required thanks to ECE operating licence • Pipe diameter: 76mm • With 200-cell HJS sports catalytic converter incl. ECE operating licence • Material: stainless steel • Plug&play • Thermo integral insulation • Optimised downpipe performance • Lower exhaust gas temperature, which spares the manifold & turbocharger • Reduced thermal load on the turbocharger • Sportier sound
