| 'SPORT PRODUCTION' SYSTEMS 4-1 or 4-2-1 CONFIGURATION The 'SP' line systems are manufactured from high grade stainless steel. This style of systems uses conventional straight header tubes, and is designed fitment on motorcycles with a standard or mildly tuned engine. Whilst no changes are necessary, performance gains can be optimised by the fitment of a carburettor tuning kit. Akrapovic strongly advise that fitment and modifications be carried out by a professional. |
