The key here is that Sam was referring to the bottom end. If you were
towing a trailer at 1800rpm's, you might be better off with a TWO inch pipe.
The point of a 3" high flow cat is to help you when you're wrapping it out
at the track going "c'mon - c'mon - c'mon!!!".

Mark, on a rc Dakota the pipe goes all the way to the cat inlet, cut
&
weld. I recommend trying the headers and Y-pipe first before going
to a
hi-flo cat. I don't know about your cat back setup, but with the R/T
stock from the cat back, the header/pipe combo runs a lot better all
through the rpm range and sounds louder at wot. I'm not going to
cahnge
anything else about my system until it becomes worn out and has to
be
replaced, and even then I won't be going to a hi-flo cat . I think
3"
all the way through is too much (as Sam is experiencing) and doesn't
have enough back pressure, in fact my truck felt slower than stock
before the pipe-to-cat welds were done, then it felt much faster.
