The Injen Technology engineers are experts when it comes to performance, PERIOD. From Cars to Trucks to Powersports, Injen has a variety of exhaust systems to choose from.

From the Investment cast flanges to the custom hangers, all Injen exhaust systems are 100% TIG welded and handcrafted in the USA and include all tubing, mufflers, and hardware necessary for a hassle free installation. Each system is uniquely designed to offer an aggressive sound that brings out some massive power. Like all other Injen products, the Injen exhaust systems are proudly built in Pomona, CA.

Additional Information

Performance Exhaust System, Part No. SES1971, 2017-2019 Nissan Sentra L4-1.6L Turbo.

Product Overview

Pump up the volume in that Sentra of yours, exhaust volume that is! The Injen Sentra exhaust has an overall diameter of 60mm to provide you with a subdued yet aggressive exhaust note. That 1.6L turbo under the hood of your Sentra will thank you, for letting it be heard. The SES1971 Cat-back exhaust system will help beef up the exhaust tone but still helps to pull the sound back a bit to prevent drone when at cruising speed. Our 2017 Nissan(R) Sentra exhaust is constructed completely of mandrel-bent 304 stainless steel, for smooth exhaust flow and maximum durability. You won't have to worry about this exhaust rusting out and plaguing your system with exhaust leaks. The Injen Sentra Cat-back exhaust provides a clean look, is finished off with a 3.5" single wall rolled polished tip. Installation can be accomplished in under one hour to get your Sentra back on the road in no time. Combine this Cat-back exhaust with our Sentra cold air intake for a complete performance package. The Injen Limited Lifetime Warranty guarantees precision craftsmanship, to keep your Sentra looking and sounding good.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
