I think the one exhaust that gives the most gains with dyno proof is Stillen. At least that's what I've come across after reading many threads. Never owned it, never even seen one so I can't really confirm it.

going uphill at a constant 2000 rpm makes my ears bleed...but its still worth it.

When you compare apples to apples, a Y pipe + exhaust or true dual, the gains are very very similar

that being said, as its been mentioned many, many many times
A Y pipe+ single type exhaust (NISMO, Fujitsubo, etc etc) has nearly identical power gains to a true dual (Borla, Stillen, etc)

Real world numbers from the 350Z sports magazine dyno shoot out. Look at torque and where the power is delivered and over what range.
Borla TD (car 2) = 8.2 Hp - 2.7 ft/lbs torque (peak values)
HP increase from 5500 rpm to 6500 rpm range. Lost HP & torque below
1800 rpm. 60mm pipe. Weighs 52lbs.
Stillen TD (car 1) = 8.1 Hp - 7.3 ft/lbs torque (peak values)
Hp and torque increase starting around 3000 rpm to redline. Lost a
little Hp & torque below 1800 rpm. 60mm pipe. 74lbs - 10 lbs heavier
than the stock system.
Injen TD (car 1) = 7.6 Hp - 5.1 ft/lbs torque (peak values)
Small torque loss at 2800 rpm. Torque gain starts at 3300 rpm. Small
Hp increase starts at 3300 rpm, maxing out from 5800 rpm to redline.
Major loss in Hp and torque below 2200 rpm. 49lbs.
Nismo (car 1) = 6.3 Hp - 4.5 ft/lbs torque (peak values)
Developed torque and Hp over wide rpm range. Torque increase starting
at 3000 rpm. Most HP increase from 4800 rpm to redline. No power
losses below 1800 rpm. 54lbs.
5Zigen (car 2) = (-3.4) Hp - .02 ft/lbs torque (peak values) Lost Hp,
no real torque gain. Most expensive. Loudest. 58mm pipe. Lightest
@ 25lbs.

I'm sure all of those manufactures have changed their designs since 03.
I know Injen has for sure.

R&D isn't free and nothing has happened to cause any of then to need to pay for changes.
Stillen hasn't.
Borla hasn't
Nismo hasn't
Injen has straight tip or angled tip or the ti The ti has the only meaningfull change where it's pipe diameter is larger and it has a H crossover.

injen added the H-pipe vs the old Ypipe set-up...which is where those number a few posts up came from.

I have the Borla TD on my 07 and love the sound! I was a bit put off when I read reports of leaks and the clamps coming loose over time so when I installed mine I welded it together and tossed the clamps.
6000 miles later and I have no complaints.

if you really want a good sounding exhaust, go with the amuse titan, it'll cost u a lot of money but, it's almost as close to a sound of a ferrari; that'swhy, i'm saving up some money.
