Infiniti Q50 [3.0t] Cat Back Exhaust w/ Carbon Fiber Tips - 504450


 

BENEFITS:

  • Mild note at idle and Aggressive note under throttle
  • Compliments the factory exhaust cut out nicely
  • Delivers an aggressive look that matches the enhanced exhaust note
  • Direct Bolt-On Installation
  • Designed and Manufactured in-house at STILLEN HQ in Costa Mesa, CA and inspected multiple times to ensure the highest quality and fit

 

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 the Infiniti Q50 3.0TT 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*.

*Results May Vary

 



 

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.

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.
