Airflow - Intake and Exhaust

Recommended Posts

Greetings members; I am new to the list and to Cayenne. Have a TurboS coming in June. I suspect this topic may generate a yawn or perhaps some reiterative frustrations; but I have read several historical posts but didn't quite find the info I was looking for on this subject.

2nd Cat Bypass: FabSpeed seems to be the dominant player. While I saw that one guy had some "service issues", it seemed to be an anomaly. There was some mention of other manufacturers, but couldn't find any specifics. Who are all the players for this product? What is the list consensus on quality among the options?

Air Intake: While most all of my forced induction vehicles have had completely new intakes and filters, some late model vehicles don't seem to benefit from replacement intakes, but do benefit from better flowing stock filter replacements in the stock air box. Is this the case with Cayenne Turbos? What's the scoop? Also, are there any noise/sound issues associated with intake mods. For example: I had a Q45 a long time ago where the aftermarket intake was 2x louder than the aftermarket exhaust -- it was almost a problem. Is this the situation with the CT?

The name of the game: Easier air in and easier air out.

Thanks in advance!
