This system bolts to the factory Y-pipe or any aftermarket Y-pipe with factory location and stock size flange. The Polished Tip will be exposed from your rear bumper giving it the Sport Polished look.  Also available in Titanium Burnt Tip style version instead of the Polished Tip. 

Tech Notes: 


  • 3" piping for maximum unrestricted flow
  • Bolts to Stock Y-Pipe or any aftermarket Y-Pipe with factory spec Flanges 
  • Made of High Quality Stainless Steel 
  • Gaskets and Hardware included 
  • Larger high flow non-restricted resonator to perfect the sound of the VQ motor


By installing our Circuit Werks High Performance exhaust system, you will not only improve dramatically the sound of your Z, but you will also gain the horsepower where you would normally drive the car. Like to a local car meet, to work, or weekend cruising around town.  The sound is very subtle but once you step on it, you can hear the deep sport tune exhaust tone.  Comes with a limited warranty from the purchase date.  High polished stainless steel, all are hand built to meet our high quality standard, then T.I.G. welded together.
