RobZ,
I installed a Stebro Sport system on my 2000 2.7 last year.
Here is another thread in case you missed it when you searched earlier.

It is straight forward. If I did it, anyone can. Some do it without removing the bumper cover. I removed mine and didn't have any major problems. You really don't need anything other than the muffler, tools and some sort of penetrant like PB Blaster helps. You should be able to do a search and find some instructions on removing the bumper cover. My recollection is the spoiler assembly was a little tricky to R&R, but I was able to manage so it couldn't be too difficult.
