Due to the complexity, the installation requires a professional shop that specializes in Cafe Racers. The installation requires installing, cutting the original header and creating the connection to the silencer directly on the motorbike. This kit does not include link pipes, and the professional mechanic must manufacture or create a link pipe and fitting. This is a universal kit, designed for transformations and customizations. Because it does not include link pipes or brackets, it requires changes to the manifold for proper installation. This is an original GPR product, developed after GPR's experience in the World Championship. It offers an innovative design, improved performance, weight savings and a full-bodied sound. Made in Italy with a 2-year international warranty. Tampering with the DB Killer welding or antitampering screws or fastener is illegal for road use within the EU directives. It is permitted only for RACING use in the circuits. The use of the open version (without the DB Killer) on roads does not comply with regulations governing circulation on the public road network. This kit is homologated for noise only. Please check whether a catalyst is necessary within your country to be road-legal and to pass any local inspections. GPR Products are plug-and-play. However, we do recommend a professional installation. If you buy online from a seller that is NOT GPR, we recommend you buy from a seller in YOUR COUNTRY to ensure that the item arrives with the correct approvals that must also comply with local legislation. Make sure before purchasing that the seller is trustworthy and offers the items that comply your road network. Each package includes the homologation certificate, assembly instructions, and a homologation code on each silencer. In case of a problem during installation, please stop the installation process and immediately contact customer care via our email Requires cutting the original header
