If the weight savings interest you, you should also maybe be interested in learning about how this has affected your weight distribution, eh? Wonder if the car handles any differently now.

I'm sure it changed it a little, but nothing that I can tell. It should be no different than when I pull the spare tire out up front for an autocross event. When I put in new seats, that will also reduce weight and change the distribution.

I guess there are many things that can change the weight distribution, but that is fine. If you calculate how much 20-30lbs changes it, it's not much.

That's pretty much what I was getting at. People like to ask about weight savings and all that stuff, but if it's not a change along the lines of 100 pounds or more, the weight savings are pretty unnoticeable.

The weight loss from the exhaust makes up for what I've gained this year by eating too much.

curious to know

What would a stock Boxster S put down at the wheels?
Is there a lot of loss due to tranny?
I'm curious because my experience to this point has been North American products.
Anybody know?

It depends on the dyno and it's calibration to give accurate numbers, but conventional wisdom says 12-15% drivetrain loss, so 213-220 hp at the wheels.

I finally have it. At the wheels (red: bone stock; violet: desnorked):






At the crank (with a 17% drivetrain loss):



Enjoy.
