As with any turbocharged vehicle, Stillen found quite a bit of power on the Infiniti Q50 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 a 26WHP and 29WTQ Gain. Those numbers are nothing to sneeze at, and you'd be hard pressed not to notice an additional 29lb/ft of torque.
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.
Also available is a unique polyurethane Stillen Rear Bumper Valance Diffuser for your Infiniti Q50 designed to complete the look and fit the Stillen Exhaust outlet tips perfectly.
Power is the primary purpose of the Stillen Exhaust System on your car. However, sound is a close second. With an authoritative growl that has become easily recognized at the Stillen trademark sound. This exhaust is mild at low RPM and comes alive when pressed into the higher RPM ranges. The free flowing mufflers keep the sound down when you want to be civilized but let you be heard when you want to let loose.
