MTC Motorsport McLaren Senna Decat Downpipes with Heat Shields

The downpipes and flanges are machined from SS304 aircraft-grade stainless steel and are a direct fit to the McLaren Senna model
These decats provide a sharper throttle response due to faster spool of the turbo
Mandrel-bent for better gas flow and maximum internal size to ensure no loss of mid-range torque
There is also a substantial weight saving in comparison to the factory catalytic converter

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.

We didn’t want to lose the warranty on the rest of the car so we used 2 of our own stainless steel lambda spacers to keep the engine light off and didn’t tune the car. They work absolutely fine.
They will take around 6 hours to install and the fitment is great. Please contact us if you need a garage to fit these as it an be a difficult job with the rear 1/4 panels off the car.
This product comes with lifetime warranty.
