Yoshimura Full Exhaust Fumes

Well... not trying to sound harsh, but really, what did you think was going to happen when you remove a device that removes air pollution? It is said that a vehicle's exhaust flow without a catalytic converter is 25% carbon monoxide. A catalytic converter converts up to 99% of that carbon monoxide (CO) in the exhaust to carbon dioxide (CO2). What your wife is smelling is carbon monoxide, which is not a good thing. You also need to consider never warming up or idling your bike either inside a garage or outside a garage with the exhaust facing into the garage. CO2 is not a safe gas to inhale, but CO is much worse both in the short term and long term. Obviously, it's what gets the job done when someone commits suicide by CO poisoning.

Classic,

Carbon Dioxide is very safe to inhale even in fairly large concentrations. Even at 20+ times it's atmospheric level you wouldn't even notice it. At 200+ times normal levels it is replacing enough oxygen in the air to start making breathing difficult but the co2 itself isn't toxic. Our own lungs produce it and we exhale co2 with every breath. People who work in enclosed agricultural greenhouses/hot houses that pipe in co2 to raise the level to 5 times what it is in the atmosphere have no problems. CO is another story and when it's present the lungs soak it up like a sponge. Even cars with functioning cats produce enough CO to be fatal in an enclosed garage.

Both co2 and CO are odorless gasses. She is certainly smelling exhaust gassed but she's not smelling CO.
