Precision-Built for Maximum Flow and Performance

Transform your McLaren’s sound and performance with EMP’s 3.5” Catless Downpipes—designed specifically for the 720S and 765LT (M840T engine). These high-flow downpipes are constructed from TIG-welded 304 stainless steel for maximum durability, heat resistance, and long-lasting performance.

Built for enthusiasts pushing the limits, our downpipes dramatically reduce backpressure, sharpen throttle response, and unleash a more aggressive exhaust tone that amplifies your McLaren’s presence on the road or track.

Designed with bolt-on fitment in mind, these downpipes integrate seamlessly with your OEM or aftermarket exhaust system. CNC-machined flanges, factory-located O2 sensor bungs, and precision brackets ensure a flawless installation.
