Overview
This catless SS304 exhaust manifold removes the factory catalytic restriction entirely from the R8 V8's 4.2 FSI — opening up exhaust scavenging from both banks at once. Heat-wrapped construction manages the additional thermal load that comes with a catless setup.
Why Upgrade?
- Catless design removes the primary restriction at the cylinder head
- Heat-wrapped construction for underbonnet thermal management
- SS304 stainless steel for durability
- Improved exhaust scavenging across the rev range
Built for the Drive, Not Just the Dyno
A naturally aspirated V8 has no boost to compensate for a restrictive manifold — every bit of exhaust scavenging lost at the cylinder head is lost for good. Going catless is the clearest sign a build has moved past stock thinking, and the heat wrap means that decision doesn't cook everything around it in the process.
