@norcalnorway How many cars have you heard of that use twin plugs? Top Fuel dragsters that make 8000 horsepower on nitromethane? It's pretty much a waste for 600hp

@FenderBassman155 Probably has a twin plug setup

How did you override the after Cat lamba censer from not sensing the Cat working and putting on the engine light.and making the ECU go into safe mode. I ask because I have the same car & want to make the same mods but I'm being told putting these De-Cat pipes on will create these problems ?

@CrudeOctane i agree, they just made the displacement in the new-ish ones too big.

5 of 12? You mean 5 of 6.. These are flat 6 cylinder motors..... ???

The last true 911 and it's ultimate evolution.
That said I wouldn't kick a 997 GT3 out of the garage.
