Well it depends what you're looking for really, there's lots of 2008 mods for Intake, Exhaust, Headers, and so on.. I have a 2009 and have the same problem, but it really depends what you're looking for.
There's tons of threads, use the search button and you will discover many things. Check the stickies.
As far as body kits go, there aren't many out there besides the 3d carbon one that everyones aware of. You have to remember that 2008 just ended & the companies have to catch up. Personally, I'd start off with intake, exhaust, beefing up the suspension, brakes & new wheels. You can take a look at my current mods & if you have any questions, just let me know.
steeda makes a short ram intake. and you can find some eibach springs on that site also. and there is f2 which makes a nice header for the 08 09 model. there are also some eibach springs for cheaper than steeda site. and thereis an exhaust kit on focussport and trubendz.
