So i ordered my rv-6 jpipe test pipe, he shipped it out the same day i payed for it and it arrived at my door the next day 
those bolts are on there hard, i had to get a breaker bar to get them off, and my car is only a year old and has never seen snow. Besides that installation went pretty good. When i removed the original pipe there was a ring of rust (just a little bit) where the old jpipe met the precats, so i used sand cloth to knock that down to make it smooth.
After install i took it for a test run and noticed at WOT mine also has a hiss, but if i drove it in manual i could get upto 5k rpm and it wouldnt hiss, only when i put the pedal all the way down. i dont think it sounds to bad at all, it sounds like my roush supercharger but quieter. I know everything was lined up properly and i know i tighten down everything tight, cuz i even snugged it up with my breaker bar. Dunno why we are having this hissing problem,but the sound seems to be coming from the jpipe and not the 3rd cat delete.
Like i said maybe in time it will go away but for now i dont mind

Okay guys here is the plan for those who dislike the hiss.
1. I am going to test a jpipe on my car and see if i can replicate the results.
2. Lets wait and see if this gets better like the precat deletes sometimes the noise just goes away after stuff wears in.
3. If the noise is permanent I will have the flex pipe replaced to see if the fixes things. I did some research and sometimes flex pipes can cause hissing.
Lets try this for now I am not satisfied until you are.

^ He said breast 
Sorry I love Family Guy.
Anyway, it doesn't seem like anyone can reproduce this hissing noise when the car isn't in motion. If I'm wrong, please correct me and post a sound clip of it.
I spoke to Richie last night about this and are pretty sure its the flex portion causing the issues. Since the flanges are smooth and the supplied gaskets are all new, the sound shouldn't be coming from there.
If there's anyone out there who is knowledgeable enough (or happens to have the time) to help troubleshoot this, I'm sure Richie will appreciate it!!
The last thing we want is for him to go broke over this and stop making parts for the TL right??

^^^ you are right! when i first got it done, i could hear the hissing lightly while being still. However, it stopped doing it (while sitting still) for some reason. BUT, the sound is still there while driving and increasing position past the 3/4 mark like others have said. in my 6spd i get this noise in every gear except 6th.....so say it is the flex portion....how does he plan on fixing this??
BTW: in no way or shape am i discouraged about this...the gains are still there and so is the fit and finish! still a GREAT product....cant wait for the front strutbar

If there is no leak around the gaskets, and all the flanges are seated it can come down to the flex pipe or the design of the merge. Usually it's the flex pipe that's at fault and stems from the internal design of the flex pipe which causes the leaking sound.

Now that this thread has made me paranoid about the hissing coming from the J-pipe and Test pipe I have been driving around for the past couple of days trying to listen for ANY type of hissing coming from the car and I cannot hear anything.
I even went so far as to have ask someone driving next to me if they can hear anything when I go WOT and even they can't hear anything. I drove on the freeway and went 3/4 throttle and nothing. There hasn't been anyone else on the other site hearing anything, I wonder why it just is happening here?
I have jacked the car up a few times now with it running and my wife inside giving it throttle while I am checking the flex pipe for any type of leakage and still nothing. It's seems really weird to me.
ifirahse and RBP_04TL: Has the sound gone away, or is it still there?

Thanks for the advice guys. I am going to check and see if they used different flex pipes on this lot. Hopefully its a easy fix and everyone can gets what the want.

I wouldn't worry too much if you can't hear it.

Got the same problem with the deletes, hiss on acceleration, just can't get rid of it. So annoying...
I believe it's the flex pipe making the noise too. Maybe just a bad batch
Richie, it would be great if you could include new gaskets on the j-pipe end of the deletes as well and some install instructions with bolt torque numbers, not everyone has a repair manual.
Thanks for working on this problem, making a great product better

Hisssssssssssssssssssssss .....
This is getting a little disconcerting ... my J-pipe/test pipe are arriving today and I damn sure don't want a hissing exhaust 
May hold off on installing the system until things get sorted out first. There's a few too many peeps with the same issue for it to be random?

Besides this issue, the pipe construction and quality is top notch; outstanding welds at all joints and good finish work at the flange joints. This exhaust seems very well constructed

I got mine yesterday as well. Nice and shiny but cut my finger on a stub/edge near the flex pipe that wasn't filed/sanded down properly.
There was one part where it felt like the edge of a can after it was opened with a can opener. Odd.
It seems the hissing is from the last batch (which I got). Hoping to install this weekend.
If the flex pipe is the issue...can it be swapped out? Anybody know?

The flex pipe is welded... so to swap it out, it'll need to be cut out and a new one will have to be welded in. PITA but I'm sure Richie will figure something out.
I'm pretty sure you got a J pipe from the "bad" batch. I'll let Richie chime in when he reads this.
Dunno yet. I'll keep you posted. Do you have plans on Saturday?

After close examination of the flex pipe ...
Here's a couple pics of my flex pipe section of the J-pipe assembly. The only thing "off" that I can see is the gap between the flex pipe and mating flange cup. Besides that, everything looks to be in order ... is this the possible culprit to the hissing? Keep in mind this outer area of the flex pipe has no exhaust sealing properties ... the inner tube of the flex pipe is actually what is sealing. This question will have to be answered by Richie ... 
Entry side of flex pipe ... nice tight seal to the "cup" joint
Exit side of flex pipe ... 2-3mm gap between flex pipe and the "cup" joint
Full shot of flex pipe mating surfaces
