3-Inch 304 Stainless Steel Downpipe/Front Pipe Combo

The PLM Downpipe and Front Pipe Combo is a performance exhaust system engineered for the 1.5L Turbo engines in 11th Gen Honda Civic models and 2023+ Acura Integra vehicles. By replacing restrictive factory components with a 3-inch mandrel-bent 304 stainless steel setup, this kit improves engine performance and exhaust flow. Each unit features 16-gauge stainless steel construction and precision CNC-machined flanges to ensure a precise, direct-fit installation while retaining compatibility with factory heat shields. The integrated 200-cell metallic core catalytic converter provides a balance between emissions compliance and increased flow. This combo is designed as a direct bolt-on installation, and the manufacturer explicitly states that no ECU tune is required to see immediate performance gains. However, professional tuning is recommended to fully unlock the performance potential of the engine. The package includes all necessary gaskets and hardware. It is backed by a one-year warranty from PLM. Please note that this kit is designed specifically for 1.5T engines in 2022+ Honda Civic (including Si models) and 2023+ Acura Integra platforms.
