What is the main benefit of using 304 stainless steel for this exhaust system?

304 stainless steel is chosen for its excellent corrosion resistance, meaning it's much less likely to rust and develop exhaust leaks over time. This material also contributes to the overall durability and longevity of the exhaust system.

Does this Injen exhaust system require cutting or welding for installation?

No, this cat-back exhaust system is designed as a direct bolt-on replacement. It does not require any cutting or welding for installation, and all necessary hardware and hangers are included for a hassle-free process.

What is the typical sound profile of this exhaust system?

The system is designed to provide a subdued yet aggressive exhaust note from the 1.6L turbo engine. It includes a 12-inch resonator specifically to help pull back the sound and prevent drone when cruising at highway speeds.

Product Details

The Injen SES1971 cat-back exhaust system is built from mandrel-bent 304 stainless steel tubing, which means the pipe maintains its diameter throughout the bends for smooth exhaust flow. This system is designed specifically for the 2017-2019 Nissan Sentra with the 1.6L turbo engine, aiming to give that small turbo engine a more noticeable, yet refined, exhaust note without excessive drone at cruising speeds. The 60mm (approximately 2.36 inch) piping diameter is chosen to balance exhaust tone with performance for this specific application.

Crafted with TIG welding and featuring investment cast flanges, this Injen exhaust is built for strength and a straightforward installation. The system includes a 12-inch resonator and is finished with a 3.5-inch single-wall, rolled, polished stainless steel tip, adding a clean visual upgrade to the rear of your Sentra. Injen states this system can provide dyno-proven gains of up to 14 hp and 12 lb-ft of torque, and it comes with all the necessary hardware for a hassle-free, bolt-on installation that typically takes under an hour. Combining this cat-back with an Injen cold air intake is suggested for a more complete performance package.

This exhaust system is proudly designed and manufactured in Pomona, California, and is backed by Injen's Limited Lifetime Warranty, ensuring its durability and craftsmanship. It's important to note that this system is not compatible with the SES1971AB Axle Back model.
