Cayenne Turbo 9YA 4.0 V8 Downpipes

New product

Not a secret the new Cayenne Turbo 4.0 V8 engine is almost identical to the Lamborghini Urus engine. That means it can sound as good as Urus or even better! By replacing massive OEM 600cpsi catalytic converters with REDSTAR downpipes we unleash all the potential that biturbo V8 has. Combined with ECU tune our downpipes will hold any power you can get even with big-turbo upgrade.

More info

More and more customers prefer catted downpipes over the catless and there is many reasons for. In case of flow and performance, catted downpipes at least on 90% as effective as a straight pipes, while obenefit with sound quality (not as raspy, deeper tone), no gas smelling, passing possible inspections with no error codes* or CEL.

Compatible Vehicles:

  • 2018- Porsche Cayenne Turbo / Cayenne Turbo Coupe 
  • 2019- Porsche Cayenne Turbo S E-Hybrid / Cayenne Turbo S E-Hybrid Coupe 
  • 2021- Porsche Cayenne Turbo GTS / Cayenne GTS Coupe 

Available Options: 

  • Double-layer heatshielding is used to protect surrounding parts, wires, and hoses against radiant heat from the downpipes.
    Integrated thermal insulation reduces surface temperature up to 70%! What makes it an absolute winner, compared to usual thermal wrapping or ceramic coatings.
    It’s very important not just for safety reasons but also affects engine performance by reducing the underhood temperature. We highly recommend this option, especially for catted downpipes.
  • HJS HD 200cpsi cats offer better flow but compromise on emissions reduction and possible random cel issues.
