i've got the Sergbo/littlebo/raccoon header and it's been great in the year i've had it on my daily driver. fit great, ground clearance like stock, no noises, just a better power band. Might be upgrading to the hytech in the near future if anyone is looking. Don't think he's around anymore so you'll have to go the high end $1K headers like ASP to get something as good or better.
