Is A Really Restrictive Exhuast Dangerous To Engine And Turbo?

[unique1]

hey guys an odd topic i know but i recently got a defect notice on my stagea its running a big cammed rb26 and t04z turbo, external gate, etc making 560rwhp and i have put a restrictor plate in the exhuast with 4 x 8mm holes in it and thats it to shut it up, so its like a 3/4" exhuast now it revs slow as and doesnt even boost up which is good, im just wondering if driving the car 40km to the inspection centre could cause damage to the engine due to the huge restriction i havent touched the boost levels or nothing i plan on cruising down slowly at about 100kmh all the way (around 2600rpm).

any chance of doing bad things to the motor long term? i have 6 x egt sensors in each runner so ill check the temps it gets to tommorow, hopefully its nuthin drastic.
