Renntech Headers
Other than being really expensive and backordered, anyone have any info. on these? Their web page has to be one of the worst. Do they require any cutting/welding like Kleemann or are they bolt on like Evo's?

Are you sure kleemann needs welding? I thought they are direct bolt on...

You can not go wrong with either Kleemann (weld) or Evo (bolt-on) headers 
Renntech headers are priced almost $2k more 
It takes about 7-9 hours to install so you would never want to take them off once they are installed. You will have to remove the primary cats with Kleemann which may give you a few extra ponies. Need to make sure that this will not cause your car to fail your states emissions.
