GPR provides original homologation documents (similar to ABE) and instructions available as drawings, video or description. If the exhaust system is used in a homologated configuration, i.e. approved according to StVZO, no separate designation is required for use in road traffic.
The exhaust is handmade in Italy, manufactured according to European guidelines and equipped with a road approval (see above) and lambda probe.
The complete exhaust system has 2 years international warranty.
The DB killer and catalytic converter are easily removable for racing use.
