A friend of mine has a FlowMaster on his 02. I was impressed by the sound
of it and he said he noticed more of a mid RPM power increase with it. Here

Yeah, I just put a Flowmaster muffler on my '93 K1500 (5.7) last month, as
well as a high-flow catalytic convertor and 3" pipe all the way out. It not
only sounds "burly", but it gave me a MPG boost and it has a LOT more power.
I originally wanted the exhaust to look like dual, with two pipes coming
straight out the back, but the guy at the exhaust shop gave me two reasons
why I shouldn't. The first was that if I ever considered putting a camper
shell on my truck, it could fill with carbon monoxide and kill someone (or a
pet!). The other reason was that it didn't add any performance, and the
long elbow on the driver-side pipe usually breaks under stress, especially
if used off-road.
It quiets down to nothing when you're cruising. It's only beefy sounding
when you're accelerating. The only downside I've noticed is that I've
developed a horrible case of lead-foot, since I just love the sound so much.
Even so, driving like an idiot, I still have about 3mpg more than I did with
the stock system.
It really seems to give an inferiority complex to these high-school kids
with their annoying lawnmower-powered imports. I just hit the gas and drown
out their noise. It also makes them want to speed past, so it's a way to
launch radar probes ahead of you... ;)

Their numbers for hp/torque increase are spot on for what I gained with
stainless headers and swept-side muffler ... right about 10%.
