Description

The Stillen axle-back exhaust system is a meticulously crafted performance upgrade for the 2016-2018 Infiniti Q50 2.0t, designed to enhance both sound and power. This system is proven to produce maximum horsepower and torque, delivering an aggressive tone under hard acceleration while maintaining a mellower note during casual driving. The system complements the factory exhaust cutout and provides an aggressive look that matches the enhanced exhaust note. Constructed from top-grade 304 stainless steel, this axle-back system ensures durability and corrosion resistance. The piping is mandrel-bent for unimpeded flow of exhaust gases, further contributing to performance gains. It features polished 304SS dual wall tips that add a premium aesthetic to the rear of the vehicle. The design makes installation straightforward with a bolt-on application, and it is proudly Made in the U.S.A.
