I run less power than Juan obviously, at just over 400whp and on my 964 3.3 turbo as you know the set up is slightly different than a 930 3.3...

After the turbo charger(K27) Currently i run a straight through pipe(cat bypass) then into the standard 964 turbo rear silencer which i believe in not restrictive however i am on my second rear silencer which appears to be blowing again!..........Question is i had a discussion with the tuner i work with during my dyno set up work and he is of the opinion that at this power output 400whp plus he is very surprised my exhaust pipework diameter after the turbo is still only 3 inches....

What opinions on what to use(non restrictive but not too loud like zork) and at what dimensions after turbo?..similar to what David has looks good,,is that 3.5 inches in dia i see??
