Like I said in my post that I deleted, SRs have no EGR. What they do have is an AIV (Air Intake Ventilation). Tha AIV allows oxygen to bypass the motor and go straight into the exhaust at idle to help light off the cat. SRs run a little bit rich at idle in stock form and the cat doesn't work just right during that rich state.
The AIV valve sits on a bracket next to the catch can. He could have been talking about that. most people/shops remove the AIV for packaging reasons when they swap it into a US spec car. The AIV tube can contact the steering column during cornering loads.
