You can accomplish the same thing by simply removing the honeycomb from your existing converter. This is of course illegal, but not all parts of the country have emissions testing... Since the muffler is stainless steel, even a car that's been in road salt will separate very easily. FWIW: any HP gain seems to be negligible. The good news is: noise level doesn't increase (I might have gutted the converters on one of my Lincolns and the empty shells could have acted like resonating chambers).
