STILLEN has long been associated with Infiniti tuning parts for as long as Infiniti has been around, creating high performance products, and meticulously crafted exhaust systems that have proven time and again to produce the maximum horsepower possible. With the introduction of the 2016 Infiniti Q50 3.0L Twin Turbo V6, STILLEN immediately went into R&D utilizing their many years of experience with VQ engines, and the results were fantastic.

As with any turbocharged vehicle, we found quite a bit of power on theInfinitiQ50 3.0TT's exhaust system. As with the intake system, the Luxury Car nature of the Q means that it was designed with Noise, Vibration and Harshness front-of-mind. That means that power-robbing compromises had to be made, the end result being that your Q50's 3.0TT can't breathe as well or make as much power as it should.

By streamlining the flow of exhaust gases and removing unnecessary restrictions in the system, after dozens of prototypes, STILLEN engineers unlocked a26WHP*and29WTQ Gain*. Those numbers are nothing to sneeze at, and you'd be hard pressed not to notice an additional 29lb/ft of torque*.

Take a listen to a Customer's Q50 with the STILLEN Cat-Back Exhaust System w/Carbon Fiber tips.

The STILLEN Q50 cat-back exhaust system has an aggressive tone under hard acceleration, but mellow during cruising, with that unmistakable STILLEN sound. The free flowing performance mufflers and tips are constructed of 304 Stainless Steel for long life, and includes a limited lifetime warranty. The piping is mandrel bent for smooth flow, and fuel mileage gains can be expected at cruising speeds.

Designed to fit beautifully into the OEM valance or as a compliment to a STILLEN Rear Diffuser, this system looks as good as it sounds. Available with three tip options to suit your tastes, choose from Carbon Fiber, Polished or Burnt-Titanium Look Tips to give your Q50's rear end that extra something it needed.

This 2.5" Y-Pipe configuration allows for better airflow. The Y-Pipe than connects to the 3" Mid-Pipe.

The 3" Mid-Pipe than carries the exhaust gases to the rear of the vehicle where it branches back into 2.5" dual rear exit.

Upon meeting the rear exhaust pipes the exhaust gases flow through the STILLEN engineered and manufactured mufflers. The 4.5" bolt-on exhaust tips enable you to adjust the tip position for a proper fit no matter what bumper or aero you choose to run at the back. Finally, the exhaust note is mild and well-mannered under normal driving conditions, but quickly turns aggressive and authoritative when under throttle.
