Phoenyx Design Racing Downpipes No Cat, Tune Included (McLaren MP4-12C / 570S / 600LT / 650S / 675LT / P1)
Catless Racing Downpipes with Included Tuning for McLaren Twin-Turbo Platforms
The Phoenyx Design Racing Downpipes are engineered for maximum exhaust flow and aggressive power gains across multiple McLaren twin-turbo platforms. By completely removing the factory catalytic converters, these catless racing downpipes dramatically reduce exhaust restriction, resulting in sharper throttle response, faster turbo spool, and substantial increases in horsepower and torque.
Each downpipe set is fabricated from 100% high-quality T304 stainless steel and finished with precision TIG welds for strength and durability. An integrated heat-stamped heat shield helps manage extreme exhaust temperatures generated during high-boost operation, extended track sessions, and aggressive driving conditions.
This package includes vehicle-specific tuning support, with tuning instructions emailed after purchase to ensure proper calibration following installation. The system is also 100% reversible, allowing the vehicle to be returned to stock at any time. All necessary mounting hardware is included for a clean, direct bolt-on installation.
