I just did this mod yesterday myself. Cut from top and tig welded it back shut. No way to tell unless you pull the muffler back off and even then if you do it right and dont have another one to compare to, you wouldn't know. (I didn't "bubble gum" it all up with a mig welder ).

All the reports are dead on. Either cover or replace the long section of perforated pipe and leave the short section alone, leaving the steel wool.

Car sounds normal at idle. Tone is the same at higher Rpms, just more volume.
