My eBay intercooler is sweet too. Too bad it's not a kit so it doesn't fit what you're looking for. One can be had for around $200 and a competent muffler/exhaust shot can weld up piping if you don't have the resources. It'll still be quite a bit less than the kits that are already put together. Granted it's more effort and fabrication and there's no customer support (or very little) so this isn't a great idea for many.
