Just weld or solder the hollow cat bodies over the straight pipe.

You better specify which lawnmowers you are talking about... I still have
a 5 horse two-stroke oil-mix gas, Craftsman lawnmower for trimming, it makes
many times more pollutants then my vehicles...

You lost your clutch because gutting your exhaust system robbed your LOW RPM
Torque, Hence you have had to slip the clutch more since your exhaust system
"modification"...
