The SOUL Sport Downpipes upgrade replaces the restrictive factory downpipes with large‑diameter 3.5″ stainless steel tubing and high‑flow catalytic cores — freeing up exhaust flow and letting the twin‑turbo V8 breathe more easily. Expect a more aggressive turbo sound, deeper and richer engine tone, quicker turbo spool, and improved throttle response. Designed to handle the demands of tuned and high‑power builds, these downpipes serve as a strong foundation for further performance upgrades.
Fits McLaren MP4‑12C, 650S, and 675LT
Retains use of factory heat shielding — designed to integrate cleanly into the stock underbody layout without bulky external modifications.
Intended as a full down‑pipe replacement — works with OEM or aftermarket catback exhaust options.
A full set of 3.5″ mandrel‑bent stainless steel downpipe sections (left and right) built for the MP4‑12C / 650S / 675LT turbo layout.
High‑flow catalytic converter cores (in “sport” configuration) to retain catalytic function and avoid Check Engine Lights or sensor/electrical issues while improving flow.
All required flanges, clamps, and hardware for bolt‑on installation — designed to fit within factory heat shields and use existing exhaust hangers.
Pipe Diameter: 3.5 inches — significantly larger than stock to reduce back‑pressure and improve exhaust gas evacuation.
Material: Thick-wall stainless steel (T304 L), with smooth mandrel bends and reinforced flanges for durability under high heat/boost conditions.
Catalyst: High‑flow catalytic converter cores (HJS HD 200‑cell, in sport version) designed to offer better flow but still maintain catalytic function to avoid CEL (check‑engine light) when possible.
Build Integrity: Each set is quality checked, ensuring proper fitment, correct flange alignment, and compatibility with factory shielding.
Increased Exhaust Flow & Turbo Efficiency — The 3.5″ stainless downpipes significantly reduce exhaust restriction after the turbochargers, helping them spool faster and more efficiently — enhancing throttle response and power delivery under boost.
Richer, More Aggressive Exhaust Sound — Freed‑up exhaust flow and larger diameter piping produce a deeper, more aggressive exhaust and turbo sound — delivering a more exotic and visceral driving experience.
Clean, OEM‑Friendly Fitment — Designed to reuse factory heat shielding and mounting points for a clean install that preserves underbody layout and maintains a “stock‑finished” look despite major performance upgrades.
Strong Foundation for Future Mods — Built with flow capacity and materials to support stock configurations or heavily modified turbo / exhaust / tuning setups — ideal if you plan further upgrades.
Durable Construction for Street or Track Use — Stainless steel, thick-wall construction and quality welding ensure the downpipes can handle heat and stress from spirited driving or track sessions.
