Ive got a fully built and boosted ebp em1, i like the stealth look but i wanna know if keeping the stock plastic pieces in the bumper is a good thing or if it will really matter. its on ten pounds for now with a hx35. as you can see it takes up pretty much the whole space and its as all right up to the lower point of the grill

 

If it fit with it on then I would leave it.

 

i think this is preference, but alot of the time it is cut out because the bumper doesn't fit properly.

 

its not remotely close enough to being a problem.

 

k cool.
