For the GS 800 we offer our last and innovative exhaust: 4-TRACK-R. It is the novelty of HP Corse and it reinterprets in mordern key the traditional mufflers with spout. To build this particular, we used the most innovative technology of ever: hydroforming. The result is obvious, the spout results to be seamless and built in one piece. A particularly efficient exhaust in terms of performance and noise abatement. Euro 4 approved, you can choose with titanium casing, black ceramic or satin stainless steel. The 4-TRACK-R is supplied with a slip-on stainless steel Slip-On link-pipe with anti-vibration springs, type approval certificate, assembly instructions.
