Hey looking for some pics/inspiration for those of you who've done a rear bumper/diffuser cut. Ran a track day with a badly adjusted single exit and one whole side is burnt and uneven so thinking of just cutting the diffuser up.

Thanks

There's a few ways of doing it -- like rwense and some other guys who have cutout the rear valance (the part you're calling a diffuser), and/or cutting the actual rear bumper cover along with the valance.

Trimming the valance like above won't require you to remove/relocate the charcoal canister (it sits in the rear passenger side portion of the rear bumper cover), capping stuff off, etc.

but here's mine
