You gained low end? Most guys report of loosing low end but gaining it up top...I've considered gutting mine but I don't want to lose what little low end I have lol.

but as far as being like a WOW difference, nothing. But why gut them, just cut them right near the weld, get some 2.5" pipe and cut it to length and weld it in, its what i did. I did about 80% of the welding with it still on the truck. I dropped the y-pipe down just to finish up my shitty welding job.

a friend of mine tuned his '04 5.3 trailblazer, then cut the converters off, and lost 20ft lbs of torque down low, with NO tune changes.
he started tuning on it, found that without the converters, it liked 4* more timing than before, it gained 30ft lbs (10 more than before the converter removal) and even more gains up top.
I'd say, if you remove the converters, make it MANDATORY that you re-tune your ride.
I'm thinking of doing this myself, as I really can't justify buying LT's for my daily-driver, both financially, and PITA wise, of working around them.
