3-Inch Mandrel-Bent Stainless Steel Downpipe Header

The K-Tuned Downpipe Header is a performance-oriented exhaust component engineered for the 2012-2015 Honda Civic Si models, available for both coupe and sedan body styles. Its unique two-piece bolted design ensures secure assembly and ease of installation. K-Tuned incorporates a vibrant flex pipe, renowned for its durability and performance characteristics. The downpipe is equipped with two O2 bungs, allowing for the convenient addition of accessories without the need for custom welding. This model is exclusively offered in a non-catalytic converter (cat delete) version, which is recommended for maximizing engine power, particularly when the motor is supercharged. Fitment is confirmed for all 2012, 2013, 2014, and 2015 Honda Civic Si models, including both 2-door coupe and 4-door sedan variants. For optimal performance and to mitigate potential movement issues, K-Tuned highly recommends upgrading to a Hasport Rear Engine Mount, which is available separately. The product is noted as discontinued, with a suggestion to see the PLM downpipe as an alternative.
