It probably would be pointless into a 3" exhaust.

It's lighter than my Lightning.

I'm guessing around 3750 lb. It's a '95 Z28 with T-tops, add a roll bar with door bars, a supercharger, an intercooler, a driveshaft safety loop, and a water tank in the trunk. It's a pig.

The only thing that reduced weight is the tubular K-member (-25 lb, maybe).
