KTM 790 Duke (2018 - 2020)S1-GP Muffler, Titanium

The sporty and stripped-down style S1-GP muffler is available with a titanium or AISI 304 stainless steel tapered body depending on the model of motorbike.

The S1-GP muffler fuses a sporty look with valued technical solutions such as bracket and fitting welding with TIG technology, while the CNC process of the machined insert bushings turned from solid allows to achieve impeccable coupling levels.
The tapered body of the S1-GP, together with the diameter of the output, the particular internal soundproofing and the set-up for housing the internal dB-killer, gives the motorbike on which it is fitted a full and satisfying sound.
