Like Zard''s own systems; this Kodlin special is made from AISI 304 stainless steel with visible Mig welds. Manufactured using high end 2D/3D lasers; robots; bending machines and skilled qualified welders for a perfect result. Comes with a plain stainless steel works finish and a powerful sound. - Compatible with stock to high performance motors - Clear stainless works finish - With a riveted ''Kodlin powered by Zard'' plate - 3 lambda sensor connections (2 large for wideband sensors for tuning; incl. adapter for OEM sensors) Note: This is a EU homologated slip-on exhaust system. Removing or modifying the Db killer on homologated mufflers will void the warranty and the homologation. Certification is valid for unmodified stock bikes; for the specific models and model years as mentioned in the product descriptions (Directive 97/24/CE; EU regulation 134/2014). The approval number; shown on the supplied relevant certificate; is stamped on the muffler and it must be presented to law enforcement when checked.
