SPDZ1 Widemouth 2017+ Honda Civic Type-R FK8/FL5/Accord 2.0T/RDX 2.0T NON Catted Downpipe Version 3

Take your 2.0L turbo Honda to the next level with the SPDZ1 Widemouth Non Catted Downpipe — engineered for unrestricted exhaust flow, improved turbo efficiency, and a sharper, more responsive driving experience.

This upgrade replaces the restrictive factory downpipe and catalytic assembly with a high-flow widemouth precision-cast inlet and smooth 3” mandrel-bent T304 stainless steel tubing, reducing backpressure and unleashing horsepower and torque across the rev range.

Designed for both street performance and track use, the SPDZ1 Widemouth Downpipe not only improves power delivery but also enhances exhaust tone, giving your Civic or CR-V a deeper, more aggressive sound.
