Does a drag race only car need exhaust boxes?

How the heck did you get a duster to weigh 3850 pounds. Cheese n rice.
Well every option the car came with was in the car it was loaded minus air. It was all original metal no glass parts. Complete mild steel cage took 2 of us to carry it without the swing outs or rear down tubes. Large after market stereo with 4 huge magnets. Heavy wall 3 1/2 inch exhaust with mufflers and tail pipes. Full factory bucket seat interior. Every hose was braided . . Oil and Trans coolers. Stabilizer bar still in place. Trunk mat and spare with jack in trunk.

And most important if you look I said with driver. You never asked me what my son or I weighed. He is 6'4" around 240. I am just a tad rounder. If you look close at the one video you can see it is turning the tires through second. It did not hook on the feathered street driven tires.

The new car will be very light all chrome moly steel we are only using the roof ,firewall, and quarters, AJE front race suspension with Strange light weight brakes. The rest from glass tech. The engine now will be all alluminum, Titanium, internals except for the light weight crank. Ordered the titanium valves tonight they are on sale right now $140.00 each. Everything else is here
