Headers are TIG welded and flanges are ground flat after construction. Headers are assembled in a CNC fixture for a consistent and perfect fit every time.

ATTENTION 2006 350Z OWNERS! - The 2006 350Z has a different steering rack than all other years, the hard lines coming out of the rack interfere with one primary on the drivers side header. This is ONLY on 2006 model 350Z cars, Nissan added a speed sensitive variable assist PS system in 2006 that changed the rack design. They left the system in the 2007-2009 cars as well, but changed the rack again in 2007 and our headers work with this rack as well. If you want to run our headers you need to modify these lines or swap out the steering rack. You can delete the variable assist system by switching to a 2003-2005 rack, or keep the system and use a 2007+ rack.
