good day, I own a 1996 sl320 and use the vehicle only on nice days, it looks and runs as new. I am wondering if my catalist is on its way out, have noticed strong sulfer smell.I live in florida and they dont have a smog test, is it possible to remove the cat and drill out the internal guts. The pipes are like new no rust on them so I thought i could drill through the opening and remove the guts. Would act as a bipass pipe.
