Catalyst SET to BDM® Shorty Exhaust BMW R100
In combination with our BDM ® Shorty exhaust system, the catalytic converters ensure compliance with the corresponding exhaust regulations in Switzerland. The catalysts are sold in a set (2 pieces).
Operating the exhaust system WITHOUT CATALYSTS IS NOT LEGAL!
We would like to point out our blog post “Does a sports exhaust really bring extra power?”.
