Our guarantee is limited to the exchange or repair of the defective part. Transportation costs and installation / deinstallation or other claims for compensation for damages are not part of our guarantee. The guarantee is valid for 3 years beginning at the date of purchase, particularly the invoice date for the exhaust system. The valves and electronic components are under gurantee for 2 years.
Parts without any authorization for use on public roads are intended for use on private race tracks only. The use on public roads is done at ones own risk and is not allowed by law.
All our sports exhaust systems are designed on the basis of serial cars. Power enhancements, turbocharger modifications or other changes in design, which entail an increase in emission temperatures, as well as any modifications on our products without consulting us before, result into an immediate expiry of guarantee.
