EOS Exhaust for Honda Civic FE/FL (22-26) Acura Integra DE4 (23-26) 3" Single Exit Catback

Make your 11th Gen Civic or DE4 Integra louder with this 3-inch single-exit catback from EOS Exhaust. It uses a non-resonated mid-pipe, so you get more sound when you get on the throttle instead of the muted factory exhaust. The 4-inch double-wall tip also gives the rear of the car a much more noticeable exhaust finish.

The full system is made from T304 stainless steel and bolts to the factory front pipe. EOS includes adapters for the supported 1.5T, 2.0L and 3-inch front-pipe configurations, so custom exhaust work is not required.

Choose either the Honda Civic or Acura Integra vehicle option. These are model-specific variants, so select the option that matches your car.

Pairs Well With

• PRL 3-Inch Front Pipe for Honda Civic 1.5T / Si and Acura Integra 1.5T: If you have a turbocharged Civic or Integra, this replaces the smaller factory front pipe and gives you a 3-inch exhaust path leading into the EOS catback. It installs after the factory emissions system.
• K&N Charge Pipe Kit for Honda Civic and Acura Integra 1.5T: The aluminum charge pipe replaces the factory intercooler pipe with a larger and smoother path for boosted air. This is for the 1.5T cars only.
• Hybrid Racing Short Shifter for Honda Civic FE/FL and Acura Integra DE4: If your Civic or Integra has the six-speed manual, this shifter gives you shorter throws along with adjustable knob height and position.
