Hey all. I have a 2005 Galant GTS and was wondering what are some of the brands, kits and mods I should look at to get things started. I have worked on bikes before (I have an 08 Vrod that I spend way too much money on) but never cars. I was thinking of doing a suspension upgrade, cat back exhaust, and some kind of ECM tuner with an air flow upgrade to start off. I have no idea where to begin finding the right products and vendors to get stuff from. Any help?

I'm in the Baltimore, MD area if anyone else is around here.
