Does a drag race only car need exhaust boxes?

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

years ago when I had my 70 Duster,( factory 340 air car) I raced it with 8 point mild steel cage, frame connectors, all steel except bumpers( so likely 50 pounds savings total there.
full bench seat/ carpet interior, full stock gas tank full of gas( didn’t want any slosh, no spare tire, I weighed probably 310 at the time, car weighed almost 3450 at the line with 3 inch exhaust out to the back, 727 transmission.
3850 is something I would love see go over the scales at my track, 400 pounds more than mine weighed( and I weighed more as a driver) is something I would stand at the scales and bet 100 bucks on
