So you have the the votex kit for a standard mkv. I actually have the same votex rear bumper that you have sitting in my shed,i'm sure you've seen its already marked for an exhaust cut out but the diffuser is the problem,it's not high enough to accomodate an exhaust cut out, i tried for ages to find the diffuser with the cut out and then just cut the bumper as marked. You could join the vortex form put a wanted out on a diffuser with the cut out,ya never know you might be lucky. It's a really nice bumper but I just got pissed off in the end and bought an ed 30 bumper, which I really like as well. It's a nice kit for a standard mkv and i'd imagine would sell well if ya wanted to flog it on here or ebay,etc. You could try ecs tuning or tm tuning. I think Ecs tuning are actually doing an offer on votex side skirts at the moment,they might have what your looking for. I bought a spoiler from them recently and I was very impressed with price and shipment.
