The MagnaFlow Competition Series Cat-Back Performance Exhaust System #19420 delivers an aggressive, attention-grabbing edge to the deep resonant exhaust tone MagnaFlow is known for, transforming your 2017–2020 Honda Civic 1.5L with dyno-proven performance and race-inspired sound.
This exhaust system features 2.5-inch mandrel-bent main piping that channels exhaust flow through three straight-through mufflers, exiting through a dual center rear configuration. The system is finished with 4.5-inch polished, welded-on, double-wall angle-cut folded-edge tips, providing a bold and sporty appearance that complements the Civic’s performance-focused design.
Exhaust system #19420 is engineered to produce aggressive exterior sound levels and moderate interior sound levels, making it ideal for drivers who want a competition-style exhaust presence. Its cat-back layout replaces factory exhaust components from near the catalytic converter back.
Developed using advanced 3D scanning technology, the system offers a precise direct-fit design for an easy do-it-yourself installation. Manufactured from 100% durable, corrosion-resistant stainless steel using CNC precision robotic manufacturing, this performance exhaust system is backed by MagnaFlow’s limited lifetime warranty. Please verify compliance with local noise regulations prior to installation.
