Phoenyx Design Racing Downpipe No Cat Tune Included (20162025 Porsche 718 Cayman | Cayman S)
Catless Racing Downpipe with Tune for Porsche 718 Cayman
The Phoenyx Design Racing Downpipe No Cat with Tune Included for the Porsche 718 Cayman and Cayman S is engineered for drivers who want maximum exhaust flow and aggressive performance gains. By removing the restrictive factory catalytic converters, this downpipe dramatically reduces backpressure, improves turbo efficiency, and sharpens throttle response across the entire rev range.
Manufactured from 100% high-quality T304 stainless steel, this downpipe is built to withstand extreme exhaust temperatures and sustained high-load driving. Precision TIG welds ensure long-term durability and strength, while the heat-stamped integrated heat shield helps manage underbody heat during spirited driving and track use.
This system installs as a direct bolt-on upgrade and includes all necessary mounting hardware for proper factory-style fitment. The design is also 100% reversible, allowing the vehicle to be returned to stock at any time. A performance tune is included and tailored specifically for Cayman and Cayman S models to maximize gains and drivability.
