Stainless Steel CatBack Exhaust
If an off the shelf, run of the mill, performance exhaust was
good enough for us The PWJDM Ultimate Exhaust would
have never been blueprinted or produced. When we created this
exhaust, we had a few conditions that we set for ourselves. Its a
decent size list But if youre planning a game changer It is what it
is So they are as follows:
1) It has to create power without creating any irritating drone
noises at the midrange where I like to keep my rev needle 85% of
the time. Like most true performance exhaust systems, double-digit
gains are expected and will vary from car to car with geographical
location and temperature differences.
2) It has to have a higher pitch sound. something more European
sounding like a true super exotics. I was tired of all the
aftermarket exhaust that was merely larger piping and sounded like
a diesel pickup truck at wide-open throttle. We accomplished this
by utilizing a unique 1-4 reverse merge design that makes you
rethink the way exhausts should be designed.
3) It has to be 3.5 to start, fairly light weight and relatively
affordable without having to go with a titanium setup. Most
GTR exhausts on the market doesnt present much of a
value in terms of what youre getting for the price you are expected
to pay. Most are made offshore in the orient. You can guess which
country Heres a hint They speak mandarin. :)
4) It has to be T304- Stainless steel and 100% hand
TIG welded with CNC machined
T304 flanges for that perfect fitment every time. We
also back purge all of our welds with argon gas so the penetration
is 100%. Penetration is a good thing! Trust me on that one.
5) It has to sound exactly the same on day 5000 as it did on day
1. We accomplished this by not using any fiberglass packing
material, which deteriorates over time. Most exhausts on the market
will sound different in a few months because the packing material
has disintegrated through all the heat cycles. With our final
version We realized that resonators werent required on all the
exhaust legs, only one of them ended up with a resonator.
6) It has to have smooth mandrel bends No 90-degree bends
anywhere in the entire system. Flow is everything for an exhaust,
too sharp of a bend and it becomes restrictive and power robbing.
For ease of install We revised it to have a V-band clamp which
helps on the install as well as shipping.
7) Since the GTR is a turbo charged sports car I
want to hear the turbos spool and the waste gates letting off. Why
pay all this money for a car to only hear it sound like a naturally
aspirated car because the exhaust is so muffled and restrictive.
Sound cancelation can be achieved in a few different ways
PWJDM through years of research and development
figured out a way of reducing the exhaust notes you dont want while
keeping the notes you want to keep without having to use a
8) It has to be sickest, baddest exhaust period! 1-4 reversed
merge split (we like to call it the squid) And has an exotic sound
to match. Well so much so Soon after we released this exhaust,
Greddy made a 1-4 version very similar to ours Sure they placed
some resonators in the piping to make it different which is cool
The funny part was that they had 4 exhausts already for the
GTR before they came out with this new version. It
just goes to show, if its that good Then its definitely that good!
It was quite flattering to be honest with you.
9) Oh yeah, It has to be 100% hand made here in the
USA and it has to be made 1 at a time.
These 9 conditions were written down And then we went to work.
What we came up with Was mind blowing! A true work of art that
truly performs as expected! At PasswordJDM, it wouldnt have been
any other way. And once again If there was an exhaust in the market
that I would have been happy with, I would have NEVER
have created this exhaust. With so many words, I can tell you how
exceptionally well this exhaust was created The one thing I cannot
tell you, is how great this exhaust sounds You almost have to hear
it in person. What we ended up with is a well-balanced exhaust that
has a note worthy of any world-class super exotic. An exhaust that
you can hear, but yet not over bearing. And exhaust that you can
feel in the seat of your pants and also on the dyno. A true head
turner that wont get you a middle finger like you would if you
rocked one of the other truck style GTR exhausts. An
exhaust that will last a life time Should also carry a limited
lifetime warranty. We stand behind this exhaust so much that it is
warrantied for life. And if you are still on the fence, I say you
should try it out If you dont like it, send it back well give you
your money back less shipping which is more than fair. We are that
confident about our products.
