STILLEN® has long been associated with Infiniti tuning parts, 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 2014 Infiniti Q50 V37, STILLEN® immediately went into R&D utilizing their many years of experience with VQ engines, and the results were fantastic.

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.

Show off the sound of our cat back exhaust with a specially molded rear diffuser that fits over the existing rear valance, creating a new aggressive personality.

Compliment this performance exhaust system with our signature CARB EXEMPT air intake system that features a Dry Filter that does not need to be re oiled. Listen to how your Infiniti Q50 will sound after installing the upgraded intake system from STILLEN®.

Match our Intake with a race inspired front splitter that molds perfectly to the lower front bumper of your Q50. This splitter is made of a durable construction which means it can survive daily driver use.
