Track Use and Important Notes
RACING - No ECE type approval. The original exhaust will need to be cut. The use of racing products and products which do not have EC approval is generally not permitted on public roads.
When fitting Remus sports silencers, cat-back systems and cat replacement pipes designed for use on closed tracks, it is advantageous to carry out an ECU remap in order to exploit the optimum performance of the exhaust system and to prevent the check engine light from illuminating.
