SYM JOYMAX 250 I [2007-2008] - Exhaust system Evo4 Road

The Evo4 Road exhaust system from GPR is specially designed for the Sym Joymax 250 I built between 2007 and 2008. This high-quality complete system made from 304 stainless steel not only offers improved performance over the standard exhaust, but also a more distinctive sound. The system includes all necessary attachments such as flanges, bushings and brackets and can be mounted directly on the cylinders without the need for structural changes.

The exhaust system is made in Italy and is characterized by excellent workmanship. It has a heat-resistant ceramic coating and has an elliptical shape measuring 90MM x 120MM. A removable dB killer allows the volume to be adjusted for racing purposes, although it should be noted that its removal is illegal on public roads and may void the warranty.

Installing the exhaust system does not require any structural modifications. GPR recommends following the instructions provided. For online purchases, the warranty can be activated by sending in the installation receipt. The warranty is for two years and includes the right to repair by return to the GPR factory or an official distributor, at the expense of the customer.

In addition to increasing performance, in some cases the use of the exhaust may require reprogramming of the control unit (ECU), especially if further modifications have been made such as the installation of a sports air filter. The exhaust system is backed by an international two-year warranty and complies with ISO 14021 zero impact environmental certification.
