Here are some airflow results measured on a Superflow SF-600 @ 20" H2O :
Stock exhaust : 221 cfm cubic feet minute
Stage 2 : 373 cfm
Open pipe - no cat - stock tailpipe : 422 cfm
New Europipe muffler : 588 cfm
Backpressure of a stock 996 TT exhaust on a stock 996 TT at 6500 rpm is 0.36 bar
Backpressure of a Stage 2 EP exhaust on a stock 996 TT at 6500 rpm is 0.15 bar
Backpressure of the new EP exhaust on a stock 996 TT at 6500 rpm is 0.080 bar
I've been told a different file would be optimal.

Damn it Mike your rubbing it in aren't you!!!! 
There is going to be a tuned file for basically 130mm cats with straight pipe..
We won't talk about resonance
