Got some numbers for you fellas.

Stock exhaust system header back weighed 100 lbs. The new catback titanium system with valve controller is sitting at 53 lbs.

The OE driveshaft weighed 22.4 lbs. The CF shaft is at 19.1 lbs. Not as light as I imagined but it's still gonna wake the car up.

Battery, Clutch/Flywheel pack is next
