Revised the downpipes and y pipes

OLD
Greddy cast o2 sensor housings 4lbs each, (-8lbs)
Stillen test pipes (around 4.5 each), (-9lbs)
Generic Y pipe (-11lbs)
Subtotal (-28lbs)

NEW
Downpipes 5.5lbs each (+11lbs)
Y pipe (11lbs)
Added misc heat wrap (3lbs)
Subtotal (25lbs)

net -3lbs

2986lbs - 3lbs = 2983lbs

Looking for facts and data over guesswork? I am in the process of weighing, removing, and replacing parts. Here are a couple of videos showing the steps and weights:

Remove the Battery and Brake Fluid Reservoir Covers
Racing Battery Install
Misc. Part Weights

I am just getting started and will post more videos to my YouTube channel- Rob Review.

It’s been a hot minute but the car is down to 2815lbs … and it might be a little lighter than that but the game continues…

A hot minute equals almost 3 1/2 years and over 118# from your last post! What did you take out? What made the greatest difference?

Probably the greddy twin kit and went to the custom front mount. Went from 20ft to 25ft of stainless steel & aluminum headers/downpipes/Ypipe/midpipe/muffler to a crazy header and about 2ft of 4” stainless. Charge pipe setup was drastically reduced. Probably a net zero gain on turbo weight, Greddy’s intercooler was relatively heavy compared to the treadston 1245 and I went from that pretty large C&R Racing radiator to a much smaller unit.

finally pulled the trigger on a dry carbon hatch and found a set of (used) fiberglass/cf doors.

Also fell in love with a set of V1 Track Wheels … still cant believe how much I like them

Nice- any idea of what static weight balance is for your Z currently?

Not 100% but with the lighter turbo setup (although it's sitting in front of the engine) I moved the battery, radiator, and water meth to the hatch ... I need to find some corner scales

For what it’s worth - been awhile but the car is down to 2820lbs per the sale at the track(drag).
