So i've been looking around and searched the forums based on the rear diffursers. I came across this one that really caught my eye and wanted to see how exactly i can make it work. We have a body shop and wanted to see what y'alls opinion was on getting it done, Prep work , etc.

This is the walker diffuser or whatever and i dont know how i feel about drilling holes into my rear bumper cause that's what it looks like for that center part to stay on.

It doesnt need to be drilled, it mounts on to the bumper with double sided tape. I had this piece and and it wasnt my cup of tea.

 

What were your thoughts on this piece exactly? I've been considering the Stillen's rear diffuser but wasn't sure since its a hefty 400bucks for that diffuser.
