catalyic converter
 

Ok I have a 96 GT stang with flowmaster exhaust now I want to know what part of the catylic converters can I get rid of without screwing with my Oxygen sensors?and I am guessing I want to just get rid of 4 of them and leave 2 on there. Is that possible? also,the flowmaster (2 chamber) kinda hummms instead of growl unless it is revving down whats that about? -all comments are welcome thanks alot

Yeah the Flowmasters have a drone at about 1900-2200 rpm. They do kind of just hum unless you really get on it. Get yourself a Bassani X-pipe with either 2 cats or non. This will change your cars sound greatly and I'm almost positive you'll love it. Bassani X-pipes are kind of expensive but I'm sure the other brands like BBK and Dr. Gas sound just as nice too.

try this
 

If you want a great rumble from your car,try the Dynomax racing bullets.I havent installed an X or H pipe yet but I love the way these mufflers sound and they are very unrestrictive unlike the flowmasters.Hope I helped.
