yeah, the bolt actions had cats, the auto's did not. Don't ask me why.. just the way the Fed's wanted it, I guess..

removing it, although illegal, is a popular mod.

Personally, I'm gonna put a Walker DynoMax system on mine.. that way, if I bend up a pipe or crush a muffler hauling the manure spreader out in the woods, all I do is call NAPA and order another one.

don't hallow out the cat,scrap it. the money you will get more than pays for the parts to replace it.
