Full systems

A full system is the complete statement: headers, mid-pipe and silencer engineered as one, with the weight savings and power delivery a slip-on cannot reach. Race-bred systems from Akrapovič, Spark, Termignoni, Arrow, Austin Racing and Vandemon in titanium, stainless and Inconel.

Full systems are where dyno tuning belongs — most are designed for race use with a remap, and that is where the advertised gains live. Expect the biggest single weight saving available for your bike, often four to six kilograms. Check road-legality notes per product: many systems here are competition-only and marked accordingly.
