"I’ve got to say, that Stage 2 package you put on my 570GT is unreal. We saw 732 HP and 930 Nm on the dyno and I’m still buzzing. The way it pulls now is just ridiculous – throttle’s razor sharp and the sound is now incredible. You and your team absolutely smashed it. Proper professional job from start to finish, and you made me feel like the car was in safe hands the whole way through. Honestly, It is a rocket now."

McLaren 570GT – Stage 2 Upgrade
We supplied and installed our Narkos Performance downpipes with integrated heatshield, followed by a custom Stage 2 dyno tune.
📈 Stock: 560 HP → Tuned: 732 HP / 930 Nm
Enhanced throttle response, deeper exhaust note, and calibrated crackles with controlled flames – all dialed in on dyno for maximum performance and reliability.

Delivering a huge performance gain you can feel in every gear. The throttle response is razor sharp, the soundtrack now features aggressive crackles and flames, and the car pulls like a completely different beast. All tuning was dialed in live on our for maximum performance and reliability.

Engineered for maximum performance, our Narkos Performance downpipes are crafted from aircraft-grade SS304 stainless steel and TIG welded in-house for strength and precision. An integrated thermal heatshield reduces engine bay temperatures and protects nearby components.

By removing the restrictive factory downpipes, you’ll enjoy faster turbo spool, improved throttle response, and significant power gains when paired with our custom Stage 2 tune – up to +170 HP and +300 Nm. Expect a sharper, more aggressive exhaust tone with the option for calibrated crackles and flames.

Mclaren 720s stage 2 tuning package and exhaust upgrade
downpipes, mclaren, tuning, ecu tuning

Stainless steel T304 Grade welded Narkos Performance downpipes to fit the Mclaren 720s. These are some of the best sounding downpipes on the market to enhance the sound of your Mclaren as well as unleashing some brutal power. With these installed the car sounds much louder with the sports exhaust and definitely makes it more of an occasion to go out for a drive over the standard very quiet system. The standard heat shields don’t need to be installed with these as they don't hold any heat. Installation typically takes around 6 hours, and once fitted, the fitment is excellent. Due to the complexity of the process—requiring removal of the rear quarter panels—we do not recommend this job be carried out by third parties. For best results, installation should be completed in-house by our team, as we are McLaren specialists with the experience and expertise required to carry out this work correctly and safely.
