February 4, 200916 yr comment_273137 HI Guys:I like the Stahl and/or Nissan Competition headers the most. They had better overall quality, especially at the mounting flange.I built that dual exhaust system for my Z when I had the Muffler Shop in the 70's. Nothing to it really. Although you want to keep it tight up under the car. No room for sloppy work there.. I used resonators in the middle in addition to two steel packs at the rear. I don't believe you can get steel packs anymore - EPA didn't like them. It was perhaps one of the best sounding systems I've had on the Z, even if it wasn't the most efficient for performance. Nonetheless it certainly gave better flow than the OEM system.The glass packs do burn out too quickly and without the resonators in the center, that system can get loud.FWIW,Carl B.
