Roberts Competition's Exhaust

[Dtsnlvrs]

found their catalog and also called them...

he said he doesn't have the tooling for it and even if i can get a group buy he wont be making any... *sigh* *cry* *cry*

Up until...oh exactly Sep 2002, you could buy the header from them directly...then they just stopped...even with all my begging, they refuse to make any more, howevr, Kirk Racing in Ala is producing a header very similar...may look to that route.

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.

There is a Kirk header for sale on eBay right now

The mounting flange does seems thin compared to a Clifford/Nissan Comp header though.
