Alright enough bull$hit, no need to blow this way out of proportion. Sure he used slang on here but I've seen A LOT worse from people who aren't on their first post. First off dance let me start off by saying Welcome to LVC. Don't let Pete scare you away, personally I don't mind him most of the time but as you can see by his title he is the golden douchebag of LVC, and several have blocked him for various reasons. Anyways, most HIDs are plug and play, you can install them yourself quite easily. Here's a link to DDM tuning:
http://www.ddmtuning.com/catalog/HID_Kits-85-1.html That's the cheapest you're going to find them and they come with a lifetime warranty. On the exhaust are you looking for performance or just a throatier sound?
