An airbag inflator diffusion system having a thin profile. The diffusion system includes an airbag inflator that is inserted into a sleeve. The sleeve has overlapping longitudinal edges positioned so that the sleeve tightly circumscribes the inflator. Engagement tabs are formed in one longitudinal edge of the sleeve and fold through perforations formed adjacent the other longitudinal edge. Upon activation of the inflator, the sleeve expands radially forming an exhaust passage through which exhaust gas may travel. The folded engagement tabs and their corresponding perforations limit the radial expansion of the sleeve.
