2003-2006 Infiniti G35. DC Sports 3-1 Polished Header for the Nissan 350z/G35 chassis is constructed from quality T-409, mandrel bent stainless steel piping, and CNC machined flanges. Every header is tig welded by hand, both outside and inside of any joints.
Terrible to install. Took all weekend. One stud was seized, and one nut stripped. Had to cut the nut off, and then use a stud extractor on the stud. No room to work with. But the headers themselves are good quality. Fitment was great. Steering shaft cleared without any modifications.
