Product Description

STILLEN is excited to release the cat-back exhaust system for the 2023 Nissan Z.  During the development of this exhaust system STILLEN engineers went through multiple different exhaust configurations and prototypes determine what would provide the best performance, best flow, and best sound.  

After months of exhaustive testing the team determined that the best design starts with a stainless steel flange precision tig welded to 2.5” tubes leading into a CNC bent and CNC machined X pipe.  During the development the team tested a true dual exhaust system and determined that it was too loud and too “flat” sounding.  Something very common with twin turbo V6 engines.  However, in an effort to get the best performance possible we did not want to restrict the engine by going from dual 2.5” tubes to a single 3” mid-pipe.  The perfect solution was an X pipe which offered a cross-sectional area of around 4”.  This allowed the team to merge the left and right banks which improved the sound tremendously without restricting the exhaust flow.  Additionally, it allowed the team to fit the largest possible collector through the narrow chassis tunnel in the center of the car.

From the X pipe the CNC mandrel bent 304 stainless steel tubes lead into a pair of precision tig welded high polished finish, mufflers.  To design these mufflers the team at STILLEN created new, proprietary, machinery to complete the assembly and welding process in-house.  This equipment along with the manufacturing procedures developed exclusively for this muffler allows the team to precisely tig weld the polished stainless steel muffler bodies and end caps leaving behind a “stack of dimes” finish with a fantastic multi-color burn trail from the tig welding process.  

To finish the exhaust system the customer has a choice of polished stainless, burnt stainless steel, or carbon fiber exhaust tips.  Additionally the exhaust system is supported by a STILLEN branded cross-brace supporting and accentuating the exhaust system.  We are extremely proud to offer this exhaust system and even more proud to continue our many decades of American manufacturing.

Features:

  • Limited lifetime warranty
  • 304 stainless steel
  • Made in America
  • Tig welded construction
  • CNC Machined
  • CNC mandrel bent
  • Dyno tested

The competition series exhaust for the Nissan Z is intended for the owner that wants to be heard.  With no mufflers, this straight piped system is aggressive and allows the NISSAN VR30 twin turbo V6 engine to be experienced.  STILLEN’s R&D team decided to move forward with the competition series exhaust because a common character trait of twin turbo engines is that the turbos suppress the exhaust tone and many people do want a more aggressive exhaust sound.  The competition series exhaust from STILLEN offers all of the benefits of an engineered, tested, and performance designed exhaust system at a low cost with a more aggressive tone than a system featuring mufflers.

The stock exhaust on the z is very underwhelming, after i installed this, it sounded and fit the look of the z way better

It sounds awesome. No complaints, though the exhaust clamp didn't work for the left, but we went to autozone and replaced it like $4 no issue. Took him about 30-45 minutes to install and line everything up. I think I got screwed on labor, but w/e my car sounds awesome now lol - you can find my exhaust on youtube if you look up this car's exhaust. No one's posting this exhaust yet.

Despite what you might think since this exhaust has no mufflers, it’s not overbearing loud at all, if you maintain all the factory emissions equipment that is. Very high quality kit with easy to follow instructions, I had my old exhaust off and this one installed in less than an hour with a lift! The titanium tip finish is the icing on the cake, since I’m using it for subtle blue accents on the outside to compliment the blue interior. Super happy with it!

Easy install, took maybe 30 min laying on my back rolling around on the floor in the garage. Sounds amazing. Super pleased with my purchase
