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 inch 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 inchflat inch 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 inch tubes to a single 3 inch mid-pipe. The perfect solution was an X pipe which offered a cross-sectional area of around 4 inch. 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 inchstack of dimes inch 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.
