Well this weekend i am going to be changing the muffler on my truck from a flowmaster 2 chamber to a dynomax bullet style. and while I am At the muffler shop i am thinking about getting the converters cut off to maximize the exaust flow. What should i do? leave the converters and just do the muff. OR cut the converters while im there? I do not have headers and dont plan on going supercharged or cammed so do i really need to cut them off? Im looking for tenths here not miracles so if theres any gain to be had i will do it. also is going from a single inlet dual outlet to a single in single out a good move or what. Truck is a 02 gmc 5.3 programmer,eletric fans,gears,thermostat,KN intake,slicks,and flowmaster exaust soon to be dynomax. Off topic here but how do get the list of my mods to come up when i make a post or a reply?

 

I hope you know the muffler guy good, because they usually won't cut the cats for just anyone because it is like a 5000 dollar fine or something. It really depends, it will be a LOT louder if you get them cut off, but I like loud so I might have it done someday. Looks like everyone is ditching the chambered mufflers, hopefully I will soon.

 

Cut the cats and install a hi flo from here.
