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?

The only problem with headers is the labor is a lot of $$$ and the hp on a N/A motor is almost nothing.

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.
