Question about old style cats

[TrapK25]

On my truck i have the old bead style cat with a cap on the top and bottom. Ive been considering removing the cat for a deeper tone but would emptying the beads out be the same as cutting the cat out and putting a straight pipe through? I currently have shorties and a straight 3 inch from the cat back and don't have to worry about emissions around here. Also I tow about 1200-1500 pounds regularly, would the larger exhaust and reduced back pressure cause a loss of power.

If you don't need a cat for visual inspection, then cut it off. If you do need it for inspection then hollow it out.

A 3" exhaust is fine. True dual exhaust with out an"x" or "H" pipe is where you lose power.

Thanks, I'll probably chop it out then because there are no inspections to worry about around here.
