I've been looking around and it seems that most homemade FMIC kits for the S60's are just as good as the kits that cost over 650$ but for half the price. Anyone have step by step instructions for how to make one? Or better yet would you like to make one and I'll pay you?? Work seven days a week so don't have to much time! Oh and exhaust. Should I just go with a custom made pipe and toss a muffler on there? I mean I love elevates system but don't want to spend THAT much money. Thanks guys, you're always helpful!
