Pictures from last March 2011 — this one-off MonoBoom for the Sport Classic has been sitting on the storage shelf since. Custom one-off built stepped/oversize headers merged into a 2-1 collector and then routed into a heavily modified factory exhaust can (cored / shortened and repacked). Use of the “factory can” was to keep all legal EPA sound level stampings in case of “visual inspection”.
Is the system “legal” — no. It’s a one-off custom built system. It “might” pass a visual inspection. A few customers we built these for have had zero problems though. Use at your own risk.
A few years ago, we built a few of these MonoBoom 2-1 systems for the S2R800 and S2R1000 using an owner supplied exhaust can or a new MotoCreations exhaust can with our own machined tip configuration. Although I really like them and loved the deep Boom sound — they weren’t popular for some reason. Maybe the marketplace upcoming might be interested now? (if so — let me know)
This single one-off set though is available currently for the mono-version of the Sport Classic. We just need to weld spring clips, ceramic coat (choose either black or titanium color) and then repack the baffle and rivet together. Price is $1850 plus shipping. (note: if system doesn’t sell by end of month, we will entertain offers for it only then)
