• The Porsche GT4 decat downpipes are machined from SS304 aircraft-grade stainless steel and are a direct fit to the car
• These decats provide a sharper throttle response
• Improved 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
• Finished in brushed stainless steel

These will fit the following vehicles:

Porsche Boxster 718 Spyder 4.0ltr 2020 onwards
Porsche Boxster 718 GTS 4.0ltr 2020 onwards
Porsche Cayman 718 GT4 4.0ltr 2020 onwards
Porsche Cayman 718 GTS 4.0ltr 2020 onwards

With these installed the car sounds much louder 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. 

With these installed you will need to tune the car and have the GPF sensors coded out, a very knowledgeable place for this would ES Motors or someone who knows there Porsches inside out.
