Getting rid of the stock h/e's and j-pipe for 993 h/e's and an M&K crossover was good for 40 lb. With the elimination of the air injection, cat and muffler eliminated another 50 lb (includes a RarlyL8 muffler).

Paul,
Thanks for the info. Are those weights adjusted after including the new exhaust system? Thanx.

Stock J-pipe and exchangers weigh 36 pounds. My headers/exchangers weigh 15 pounds.
Stock Catalytic converter with muffler weigh 42 pounds. My single out muffler weighs 12 pounds. Total for the OEM basic exhaust is 78 pounds; my system 27 pounds, a 51 pound or 65% weight reduction for the rear of the car. Most if not all aftermarket systems weigh a bit more than this but still a substantial savings in weight right where it is needed most. Free power through weight reduction, you don't see that on a dyno, ha!

I know that most dealers on here will have much to say about their products, but I was more interested in these cars that make loads of power using the stock system (stock header system only). If you look at some of those builds that I posted, there is not a whole lot done to the motors yet they are wayyyyyy up there in the power department - and all of 'em use the stock header system. Is not that interesting?

Yes. Stock 993 heat exchangers are 11 lb each. The 964 turbo heat exchangers were almost double since they are much longer. The crossover with turbo flange was 7 lb. I weighed the j-pipe at 20 lb, the cat at 25 lb, air injection at 10 lb and suitcase muffler at 25 lb. I was using a bathroom scale so Brian's weights may be more accurate or maybe there's a difference between 930 heat exchangers and 964 turbo heat exchangers; I'm not sure.

The weight I quoted was only the 930 exchangers an J-pipe, nothing else as this is what my headers directly replace.

Kurt:
How's things? Are those headers the ones that came with the engine from Brumos? Pat
