02 Z06, catback exhaust because it was so freaking loud and nasty. Already had headers. Also the cam. It's still the only car I had with a lope, and in addition to making 35whp more, the sound and movement of the car idling made me feel like the car was alive and just waiting to explode off the line.
08 Z06. 345 Nitto Invo tires because the stock goodyear runflats were so harsh, noisy and had terrible grip. Great upgrade. But the catback exhaust (B&B PRT, $1400 fawk) made what was a fast car actually sound like a fast car. Still love starting it up, driving with the windows down, decelerating/engine braking, and screaming it up to 7,000rpm. Way too tame with the stock system. Oh, and drag radials for the track. Nice having grip in 1st gear.
