Upgrade the performance and sound profile of your McLaren 720S with the STRATEC™ Hi-Flow 200 Cell Sports Catted Downpipes, engineered for maximum efficiency, reliability, and power delivery. Designed using high-grade T304 stainless steel and precision TIG-welded construction, these downpipes dramatically improve exhaust flow while maintaining emissions compliance for street-driven setups.
Performance & Sound Enhancement
Sharper Turbo Response
By reducing restriction immediately after the turbos, STRATEC™ downpipes allow the turbochargers to spool faster, improving throttle response and mid-range acceleration.
Aggressive Exotic Tone
The 200 cell high-flow catalysts open up the exhaust note, delivering a deeper, more pronounced sound without the excessive rasp associated with catless systems.
Lower Exhaust Temperatures & Backpressure
Engineered to reduce thermal load and backpressure, these downpipes allow the engine to breathe more efficiently—enhancing reliability under spirited or track driving.
Dyno-Proven Gains
Typical gains observed:
-
+45–55 HP on stock calibration
-
+120–140+ HP when paired with tuning
Construction & Craftsmanship
T304 High-Grade Stainless Steel
