We make no claims or false allegations regarding emission performance for street or motorway use. Some parts are not appropriate for street use in some countries where local regulations prohibit its use. Some products listed in the online catalog are compatible only for off-road use. Local regulations and some laws prohibit the removal, modification, or rendering inoperable of any device or design element that affects vehicle emission or safety in a vehicle used on public motorways. Violation of such laws may result in the owner or user being fined or being incurred penalties. We strongly advise you to check the local laws in order to be sure you comply with them before you purchase any parts. Please be aware that installation of performance products may void a manufacturer's warranty coverage, if any, on your vehicle, and that vehicles modified by the use of performance parts may no longer lawfully be used on public highways. Dealers, installers, and end-users undertake full responsibility for all costs and risks associated with the purchase and installation of these products. The majority of the items sold on our website are designed for and are compatible with European vehicle fittings only, and many are limited to a specific make or model year. It is solely the consumer's responsibility to ensure the products being purchased are compatible with the intended vehicle make, model, year, and current performance application. As most aftermarket products are designed and engineered for compatibility with OEM components, the consumer also undertakes all responsibility and risk associated with any potential conflicts, damages, failures, or problems that may arise from the use of multiple aftermarket products.
