Free up the exhaust directly behind the turbo without switching to a catless setup. This EOS kit pairs its high-flow catted downpipe with a 3-inch front pipe for the 11th Gen Civic 1.5T and 5th Gen Acura Integra 1.5T.
The downpipe uses a 400-cell GESI G-Sport catalytic converter with a 4.5-inch outer diameter. GESI rates the converter for applications making up to 850 horsepower. EOS says the system does not require an ECU calibration and is designed to work without triggering a check-engine light.

Tuning and Check-Engine-Light Information
EOS advertises this downpipe and front pipe combination as a no-tune upgrade that is designed not to trigger a check-engine light. Its product page also includes a separate disclaimer stating that a check-engine light is still possible, so CEL-free operation cannot be guaranteed.
Exhaust leaks, damaged oxygen sensors, existing diagnostic codes and other engine or exhaust modifications can also cause a check-engine light.
Emissions Information
The included 400-cell GESI G-Sport catalytic converter is advertised as EPA compliant. This applies to the catalytic converter and does not make the complete downpipe assembly CARB exempt.
EOS does not publish a CARB Executive Order number for this downpipe and will not ship it to a California address due to California Vehicle Code Section 27156. EOS also labels the complete assembly for off-road use.
Before You Buy
