Take your Honda Civic's performance to the next level with the SPDZ1 2.5" Catless Downpipe & Front Pipe. Engineered specifically for the 2016-2023 Honda Civic 1.5L Turbo platform, this complete turbo-back upgrade dramatically improves exhaust flow by replacing the restrictive factory catalytic converter and front pipe.
Manufactured from premium stainless steel and precision TIG welded, the SPDZ1 downpipe is built to withstand extreme temperatures while delivering improved turbo spool, quicker throttle response, and a deep, aggressive exhaust tone.
Whether you're running a stock turbo or planning future performance upgrades, this is one of the most effective bolt-on modifications available for the L15B7 engine.
Unlike restrictive OEM components, the SPDZ1 system is designed to maximize exhaust flow immediately after the turbocharger, allowing exhaust gases to exit more efficiently.
