Best Exhaust: STILLEN 2016 Infiniti Q50 Cat Back Exhaust
It’s no secret that turbocharged engines thrive when allowed to breathe. Naturally-aspirated engines rely on some back pressure to create a scavenging effect to help maintain exhaust gas velocity. By contrast, turbocharged engines and particularly, the turbocharger(s), function most efficiently when the exhaust offers the least amount of possible resistance.
When Infiniti released the Q50 and Q60 with its new twin-turbocharged VR30DDTT engine, a new chapter in the performance passenger car segment had begun. Drawing on its experience with the VR38 engine that powers the mighty GT-R, the sturdy and underrated VR30 engine relies on its twin Garrett turbochargers to generate boost pressure. When allowed to breathe, the turbochargers really come to life.
STILLEN’s recently developed Short Ram Intake System (402856) (402856DF) has already proven to help produce incremental gains of over 20 horsepower and 33 lb-ft torque to the wheels. Employing years of engineering and manufacturing experience, along with hours of testing on its in-house Dynojet Dynamometer, STILLEN proudly presents its Cat-back Exhaust System for the 2016+ Infiniti Q50 3.0T Silver Sport and Red Sport (p/n 504450, 504451, 504452).
In the quest for the greatest gains possible, STILLEN engineers worked tirelessly to optimize this exhaust system. After several design revisions and numerous prototypes, this Cat-back Exhaust improved output with a best incremental gain of 21.37 horsepower at 4,750RPM and 23.94 lb-ft torque at 4,780RPM.
The Best Exhaust: STILLEN 2016 Infiniti Q50 Cat Back Exhaust features T-304 stainless-steel construction for corrosion resistance and durability, along with slip fit connectivity for weight reduction. The 3-inch mid-pipe mates to the catalytic converter and splits into two 2.5-inch axle-back mufflers. The mufflers terminate in your choice of three different exhaust tip finishes, including carbon fiber (p/n 504450), stainless steel (p/n 504451) and burnt stainless steel (p/n 504452). The 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. You can also purchase the other tips separately in the case that you want to change up the look of your exhaust.
