I've been looking for upgrades for the Crossfire for some time now and have been unsuccessful. So, the past few days, I've been looking for upgrades for the SLK 320 and here is what I've found:

I'm not sure, maybe all of these sites have been discussed previously, but I thought I'd throw them out there for you all. Please let me know if you find anything interesting.

I have also sent an email to SuperSprint because I read a lot of posts that mentioned their exhausts for the SLK 320, more specifically aftermarket headers. I'll let you know what they say.
