Stock vs. aftermarket parts weights

I'm considering putting my Boxster on a weight loss diet to make it into a fun track car. It's a '99 base with a 3.4 motor. It already has some aftermarket parts and I would like to find out how much of a difference there is in weight from the stock parts just to see how far ahead (or behind) I'm already at. Here's the list:

1. H&R coilovers vs. stock suspension
2. Borla catback exhaust vs. stock muffler
3. Fabspeed cats vs. stock cats
4. Ebay headers vs. stock manifolds
6. Rear Aerokit 1 vs stock lid (the Aerokit 1 replaces the stock trunk lid with a fiberglass lid & wing and removes the pop-up spoiler and motor)
7. 3.4 motor vs. 2.5 motor

Any input is greatly appreciated. I think a 200-300 lbs weight reduction from stock plus the extra power will make for a fun weekend track/autoX/backroads toy

Here's a 2.5 which had a 3.4 put in and went on a weight saving programme.

The stock 2.5 with fluids weighs 580#s... Dunno how much the 3.4 weighs.

It should be very close since it has bigger holes.

I started to think about it; bigger holes, but bigger things in the holes... IDK my brain started to hurt. LOL
