[Kreissieg] Ferrari 458 exhaust development progress!
#14
Aug 5th
We start to take apart the exhaust system.
Underside of 458's Transmission and Engine
Here are photos of stock exhaust system.
Note that when valve open, the exhaust gas goes thru all three pipe.
When valve closed, the engine uses only center pipe.
It seems like efficiency of catalyst has been increased significantly.
Overall muffler/catalyst package is super compact considering increased emission regulation and ect.
btw, another 458 arrived.
