it's very easy (although i don't have an s4r). it's actually easier than on other monsters because the emissions cannister mounting bracket doesn't tie into anything else.
1 - follow hose from emissions cannister to gastank. disconnect this hose from the emissions cannister and run it down the rear of the engine parallel to the other hose you see running back there from the tank.
2 - follow the other hose from the cannister to a "t-fitting" that splices it into two hoses. follow each of these hoses to a fitting in your intake manifolds. loosen the clamps that secure the hoses to these bleeder fittings and remove the hoses. then unscrew the bleeder fittings from the manifolds.
3 - plug the holes in the intake manifolds the those bleeder fittings left with short M5 bolts. use high-temp locktite to secure them. just "snug" tight. don't over torque 'em.
4 - unbold the cannister bracket and toss that useless P.O.S. in the garbage....
now, don't get me wrong. i'm happy to be "green" when the system works. if this emissions do-hickey resulted in a closed system, then hurrah for the EPA. but remember that other hose running down from the tank? that's an overflow line in case you overfill your gastank. it runs directly from the tank to the open atmosphere! "duh!!!" so why bother with this silly cannister? you're PLUGGING the intake manifold bleeders anyways. silly silly silly....
by the way, if you'd like to be a bit "cleaner" a
