Product Description

 

 

The Fabspeed Supersport LT Style Exhaust for the 720S replaces the heavy, restrictive factory muffler system with a high-flow, performance-oriented pipe setup — delivering a deeper, more aggressive sports-car growl and noticeably improved engine responsiveness. Designed to significantly outflow the stock or even factory “race option” exhaust, this exhaust refines the sound signature while unlocking serious performance potential, giving your 720S a more exotic, track-ready exhaust character with everyday usability.

Fitment Notes

  • Compatible with all 2018+ McLaren 720S vehicles (coupes and spiders). 

  • Bolt-on “cat-back” style replacement with no CELs or tuning required. 

  • Intended as a full rear-exhaust upgrade — replaces the OEM muffler system entirely.

Included

  • High-flow stainless steel exhaust system (muffler assembly and mid/rear piping) built specifically for the 720S exhaust layout.

  • V-band flanges and all required hardware for direct-fit installation with factory components.

Product Specs

  • Material: TIG-welded T304L stainless steel, 3.0-inch (76 mm) diameter piping for optimal flow and durability. 

  • Flow gains (dyno-tested): +55 wheel-horsepower (whp) and +54 ft-lb torque, (when paired with catted downpipes) along with a rear-end weight reduction of approx. 9 lbs compared to the stock muffler system.

  • Sound: Produces a “675 LT-style” sport exhaust note — richer, more aggressive, exotic, and more pronounced than stock.

  • Fitment: 720S 2018 and newer, both coupe and spider models.

Product Features

  • Significant Power & Torque Gains — Dyno-proven +55 whp and +54 ft-lb, unlocking more performance across the powerband.

  • High-Flow Exhaust Path — Oversized 3" stainless piping reduces back-pressure, enabling the twin-turbo V8 to breathe more freely and spool more cleanly.

  • Aggressive, Exotic Exhaust Tone — Crafted to deliver a deeper, more resonant, and exotic supercar soundtrack reminiscent of flagship McLaren models.

  • Weight Reduction & Responsiveness — Shedding roughly 9 lbs from the rear helps improve throttle response, handling feel, and vehicle dynamics.

  • Bolt-On, Factory-Compatible Fitment — V-band flanges and factory-matched mounting points let it bolt directly in, simplifying installation and preserving OEM architecture.

  • Track-Capable Yet Street-Usable — While aggressive in tone and performance, the system remains engineered for street and road use, balancing real-world usability with supercar feel.
