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

Corrosion-resistant, durable, and temperature-stable under extreme conditions.

Precision TIG Welds

Hand-finished welds ensure maximum structural integrity, longevity, and a clean motorsport-grade appearance.

Integrated Heat Shielding

Each downpipe includes high-grade thermal shielding to reduce engine bay temperatures and protect surrounding components.

Brushed Stainless Steel Finish

A clean aesthetic upgrade that matches STRATEC™’s premium build standards.


Fitment
