Question- What is the weight of the Porsche factory exhaust?
Folks-
The aftermarket suppliers are making claims about 20-50% decrease in weight, I assume not including the weight of the headers.
Does anyone know how much the 997 Turbo factory exhaust actually weighs?
Thanks in advance - Gerry

They're getting the first one in on the 20th of this month which I decided to go for.

I bought mine from them and it was made in germany, not the UK and has no resonnance whatsoever, I have no clue what your guy is talking about.
Also, it does have the heat shield like the stock exhaust and I would not buy an exhaust for the TT without the heat shield.
Just wanted to give you the heads up and good luck either way.

These were sent to me by a friend in Germany. The results are not quite 20 NM and 25 PS probably because the Porsche typically puts out more than specified.
Enjoy.
Enjoy.

Folks-
From what I can gather, given about the same configuration, here are approximate weights of the aftermarket exhuasts, although it may be "comparing apples to oranges" in some cases:
FABSPEED = 36 lbs
CARGRAPHIC = 34 lbs
TECHART = 26 lbs
9ff= 26 lbs
AWE = 25 lbs
Tubi = 20 lbs
IPP Titanium = 11 lbs
They all claim about a 20-30hp gain.
Thanks - Gerry

Thanks for sharing those dyno curves - I still think even Maha chassis dyno's can't give accurate numbers on these turbocharged 4WD cars due to many factors.....
I am sceptical about how the 997tt with the Cargraphic exhaust appears to have LOST ~22PS at 6300rpm - In reality this is where it should still have gains but probably due to air flow in the dyno cell this spurious curve is produced ?
