3 Inch Downpipe & Front Pipe with High-Flow Cat

The PLM Power Driven Downpipe and Front Pipe V2 combo is an exhaust upgrade engineered to improve flow and exhaust sound for the 2017-2021 Honda Civic Type R FK8. Constructed from 18-gauge 304 stainless steel, this version 2 kit features a high-flow catalytic converter to balance emissions compliance with performance gains. The assembly uses 3-inch piping with precision CNC-mandrel bending to reduce backpressure, paired with robust .38-inch thick CNC-machined flanges for a secure, leak-free seal. Note that when connecting to stock exhaust piping, smaller bolts and nuts are required due to the specific factory piping size. The revised V2 design maintains compatibility with factory heat shields to provide continued protection. All necessary installation hardware and gaskets are included with the kit. For those seeking optimal performance results, it is recommended to upgrade the rear engine mount to a stiffer version to minimize engine movement. This product carries a one-year warranty for peace of mind. Please verify that your vehicle is a 10th generation FK8 Civic Type R (2017-2021) model before installation.
