Berk Technology Test Pipes
I do get the hissing sound but they broke in a little and is not bad at all anymore I don't even hear it most of the time.
Enthusiazt my friends over at Nissan were telling me to make sure they when you tightened it to make sure it's not to close to some bracket or metal piece. I would lift your car and have a friend rev it while you look to see what's causing the rattling. Might be an easy fix.

sorry for the late reply..the noise comes from the y pipe right between the test pipe and the flex joint on the y pipe. It hits the floor of the car. i removed the heat shields so i know it is not this.
I have Berk test pipes on my 05 Z.
There is also a weird sound like something sucking air or leaking air.
All the pipes are tighten up for sure. I guess it is the way it is.
Also, after like 1k mile, I got cel light.... hahahahahahahahaha
Where is the ~95% cel fix ?

I ordered some Berk Test Pipes for my 2006 350Z from B2AutoDesigns which was GREAT to deal with. It shipped the next business day (Ordered Sunday) and they were VERY easy to contact. Also had free shipping. Will be doing business with them again, anyways upon opening the box Berk gives you brand new bolts, pipes, gaskets, and even a poster. Thanks Berk.
Upon installing it took me about 45 minutes to get 2 bolts off because my impact gun couldn't fit and I didn't have an extender. So I took it to Nissan at about 10:00 pm since my friend works there and used there bay along with there tools. Besides getting the rusted bolts, install was very very simple. I guess thats why they call it bolt ons. It took about 45 minutes to get the bolts off and about 20 minutes to put the new pipes, bolts, and o2 sensors on.
Test Pipe Review (Keep in mind I have a Borla Exhaust that came with the car):
The exhaust is much louder, sounds a lot deeper, and much more aggressive. Since the pipes aren't resonated it does have a decent bit of rasp, but it's not as bad as most people describe so far I don't regret it and the sound makes up for it. Acceleration seems like it is better then before. As far as horsepower gains I'd have no idea without a dyno. The only reason I got these was because of the price and the sound mostly.
Would I recommend these?
I'd say to anyone who doesn't mind some rasp, and a much louder, deeper sounding exhaust system. Yes.
Hope this helps people who are considering test pipes. I will upload a video once I find a good enough video camera for the sound.
Thanks for the read.

Would these fit a 03 350z also cause everywhere I look it ways 07 and up??
Just got my TopSpeed Resonated Test pipes installed. I have a Borla True Dual. The sound was a lil to stock so I wanted a little more. So far I love the sound, however I have this nasty metallic rattle rite where the H pipe is. It sounds like metal on metal only when decelerating. I told the shop when i picked up the car and he tells me this is rasp. NO FN way this is rasp man. This sounds like metal on Metal. Its consistent, and may cause me to remove the pipes all together.

Berk thumbs up!
I got test pipes professionally installed today. Fair price and quality workmanship.
No, zip, none CEL upon firing it up. I have original Y pipe but had resonator cut out and straight piped to a dual out Flowmaster with stock tips. The car is a lot louder, aggressive and thunderous. Definitely a head turner!! Great addition to the following:
Flowmaster
Motordyne 5/16" plenum spacer
NWP 75mm bore throttle body
K & N Air charger/cold air intake.
Uprev tune is next on the list.
The Berk Test Pipe w/CEL fix is what I highly recommend. Also, If you're not keen on working on exhaust, buy the pipes and have them professionally installed

personally I like the odor.. hehe. Hopefully I can get sensors tuned out down the road. BTW is the Y pipe (stock) constrictive? Might I consider replacement?
Ive had these for years and took them back off the car so i think i can describe them pretty well. I put them on at the same time as a catback back in 2012 and the car was just loud and it felt like it was a bit faster. The only problem was that i got a CEL but i was not tuned at that point. I took them off later cuz wasnt driving the car as much and it needed to pass inspection and holy **** did it quiet it down, I even felt like it was a little bit dronier. after 4500 rpm felt like there was something missing so it was then that i realized the difference was huge with and without them. The rasp was gone it never sounded like it was screaming anymore 2006 rev up btw. I would much rather keep them on but inspections are a thing.
On an unrelated note i was wondering if HFC will give me the same kind of performance and sound gains or at least similar?

Well got everything completed. Got Megan Y pipe installed, had to replace muffler due to a baffle breaking loose. I switched to a Magnaflow muffler that's less offensive sounding. Finally, I went to Dynosty and had it dyno tuned. The result is a fair 256whp. Not shabby for a naturally aspirated setup.
