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 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 benefit with sound quality (not as raspy, deeper tone), no gas smelling, passing possible inspections with no error codes* or CEL.
For the Cayenne E3 we offer selection between 200cpsi HJS HD ultra high-flow catalytic converters and 300cpsi HJS HD Euro 6+ high-flow catalytic converters.
-200cpsi cats offer better flow but compromise on emissions reduction
-300cpsi cats with ultimate precious metal loading offer the best emissions reduction on the market and provides CEL-free operation even on the newest 2020 Euro 6 cars.
