Yes. Remove the cat for either a straight pipe, or resonator. HKS silently discontinued their “catless” downpipes in the U.S. around 2021 for mentioned reasons

Is is still legal to saw off you cat and weld a length of pipe in? I guess it still is if you can drive 60's cars, so what's the point?

  Legal in what respect? It wouldn't be legal to drive it

    So it's only legal to drive a catless car if it was manufactured that way 50 years ago?

      Correct. Federal prohibits tampering with or disabling lavatory smoke detectors I mean emissions equipment. The loophole is that it doesn’t apply if you never take it off private property.

  It has never been legal in the US to remove any emissions equipment on any vehicle that is to be driven on the street. Even if it is outside of the smog check window, it still can not be removed or tampered with.

  No lol.. This is the EPA's whole argument. You can't modify the factory emissions output to go below the required output. People like the Diesel Brothers from the Discovery Channel settled for like $3 million USD with the EPA for selling and promoting emissions defeat devices like tunes and straight pipes.

ok, I've never heard the word catless but I've definitely driven vehicles that had a pipe welded in place :) I or a family member has acquired a few vehicles where the catalytic converter was cut out by thieves, and I've done both so I can tell you from experience that it's the difference between $15 and $800 (parts and labor). Having grown up extremely poor, sometimes families make those decisions because they don't really have a choice. Thankfully nowadays I do so I tend to err on the side of being a good citizen but personally will not judge anyone who choose s to weld a pipe in place rather than spend the exorbitant amount necessary to replace it, especially considering it might just get stolen again.
