| Felix, not sure why the pipework didn't fit your bike but as soon as we got it back it went straight out with no comeback so I'd assume it was down to an inconsistency with the way particular bikes are put together at the factory, an issue that affects one or two other products also...
Anyway, we have various exhaust options for the S4R and we have Ducati Performance silencers in stock but in my opinion the Sil Motor is the best option for out and out performance as it comes with oversized pipework (48 or 50mm). Full details on the spareshack.com site or feel free to contact me directly...
