A new guy here looking for advise on tuning a '04 45! Anyone with parts, shop, or performance tips, I'm willing to listen. I've been stock far too long, and would like to add some bolt on performance in all areas of my FX. I am considering an Eibach spring kit, and I've already added a Stillen front brace. I would like to improve my intake and exhaust, but need some direction in these areas. Any ideas would be greatly appreciated. Thanks!
