Injen 06-09 Civic Si Coupe Only 60mm Cat-back Exhaust w/ Titanium Tip

Injen Technology is well-known for making performance parts for a wide range of vehicles, and this cat-back exhaust system is a prime example of their expertise for your 2006-2011 Honda Civic Si Coupe. If you're looking to give your Si a more aggressive sound, unlock some extra power, and improve its overall appearance, this system is designed to do just that. It's built to bring out the best in your car's performance.

This system is constructed from 60mm, mandrel-bent 304 stainless steel tubing, which ensures smooth, unrestricted airflow for improved performance. Mandrel-bending means the tubing keeps its shape and size throughout its entire length, helping to maximize exhaust flow. The exhaust is TIG welded and handcrafted in the USA, featuring investment cast flanges for a solid connection and custom hangers for a proper fit. Injen's dyno-proven results show gains of up to 5 horsepower and 4 lb-ft of torque. The system includes a classic round JDM-style rear muffler and a striking 4.5-inch burnt titanium tip that adds a unique visual flair.

Installation is designed to be straightforward, with all necessary hardware and tubing included. No cutting or welding is required, making it a hassle-free upgrade. This specific system is made for the Coupe models only, so be sure that's what you have before ordering. It's a well-built package that combines performance, sound, and style for your Civic Si.
