So are any aftermarket headers out there which does not rattle/vibrate or do other unwanted noises ?
For instant how are the Mugen headers, do this have any of issues you guys mentioned ?

Keep the voting up, as this will really help me (and others) figure this out if possible!

06 6MT with CT header, RT Cat, CT cat back, no rattle issues with or without a/c on. Occasional hiss under acceleration when it's cold, but after a few minutes of driving it goes away.

Another Update!
I got my new Napa exhaust hangers that JTso had recommended so i decided to try this in slow incremental steps. Therefore, i only replaced the first hanger by the resonator behind the CAT. It took me about 10 mins as i kept needing more WD-40 as lube to get it off. Just for anyone else that tries this, take the top section off first because there is less corrosion and it then gives you more leverage for taking it off the bottom one. It def rasied up the center of the exhaust a little bit as you could see the stock one had slightly stretched a little even though i only have 9k miles on the car.
Anyway, the results were interesting. There obviously is still the vibration its not going to fix that but it did help a little bit with the noise. The noise from the vibration actually seems to have shifted back to the end of the exhaust so i think i am now going to try and replace the ones in the rear and see if that makes a difference.
I also want to get to Napa with the existing flex pipe hanger and see if i can find a poly one to replace that one do allow it to move, BUT not as much and i really think this will help a little more.
Again, i am taking a slow and steady approach to this, as well as cheapest solutions first, because i want to see how the system reacts to certain things.
The next few things on my list are:
1. replace rear hangers
2. try and find a stronger replacement flex pipe hanger
3. remove the CAT heatshield for resonating frequency (worth a shot)
4. spring washers or the like at the flange of the flexpipe and CAT

I replaced that same hanger and noise reduce but over time it gets over strechted to the point that its no good.
Still need replace the 3 hangers in the back i also replaced the 2 in the far rear they were a bitch to get on and off.

I have the CT header and I haven't noticed any noise in awhile. I still get a slight vibration but nothing I would call a "rattle". There is no sound associated with the excess vibration the CT header has.
I've had my header on for the better part of a year now.

Got an 04 AT.
UR pulleys, Comptech header, oem exhaust. Got slight rattle when they were on my car. I solved the problem when I replaced the rubber hanger with a new oem one.
Installed a RT cat this August. No rattles til about early october. I believe the rubber hanger as stretched and is loose to the point where it rattles on idle with AC and lights off.
Sometimes the header doesnt rattle but the end exhuast cans rattle.
I've inspected the rear part of the exhaust and noticed that the rubber hangers are loose as well.
It seems at low RPM with the oem hangers they stretch after some time due to the vibration of the air flow at low rpms that you guys mentioned around 670rpm. ONce the rubber hangers stretch to a certain point the entire piping from the header down to the exhaust tips gets loose and vibrate.
Im also going to see what hangers i can replace to reduce the vibration, but no matter what it will continue once the rubber hangers stretch.
Would it be suggestable to say weld parts (using metal strips to connect the frame to part of the exhaust ) onto part of the bottom part of the car so that its stationary. It should stop vibration??
I'll take it to a welding/muffler shop and try it out perhaps. If it doesnt work i'll just cut the metal rods/strips.

I am leaning towards the same thoughts about the rubber hangers and will try to find a better flex pipe hanger this weekend if i can or maybe get a thicker one.

Thinking about this more. It would be possible to weld the end part of the exhaust onto the car.
However, the header section can not be welding since the header shifts slightly when you move it onto gear from P to D.
What I usually do when im stop at redlights is shift the car into N and there's no or very minimal rattle in that gear.

The reason the exhaust is on flexible hangers is because the exhaust isn't isolated from the vibrations of the engine. If there were some kind of vibration-absorbing connection between the engine and the exhaust, then welding the exhaust downstream of that point would likely be less risky.
The best solution to fixing the stretching-rubber-hangers issue is to find polyurethane hangers. They are stiffer than rubber and stretch much less. It's probably going to do one of two things: A: Rattle more, since they're stiffer, or B: Fix the problem more permanently than the OEM rubber hangers.

Due to the weather and lack of time this weekend, nothing to update. I will be attempting to upgrade the flexpipe hanger this weekend to see what i can make of it! I'll let you know then but in the mean time, please keep the poll going......

Update/question
So i jacked the car up saturday morning, took the flex pipe hanger off and took it to Napa. The guy at Napa opened up his book and didn't even have my car in his book!! The book was dated as 2006 but didn't even the TSX in it. He wasn't really into helping me out but told me to go to an exhaust shop as they should have something. I asked him to check the accessories in the back of the catalog and found one item that looked like it could work but it ended up being longer than the stock one, which is NOT what i'm looking for.
I then went to an exhaust shop and the guy said he had never seen a hanger like that before and had no idea where to even try to look into getting one.....awesome! Last try i went to Autozone where the guy checked his computer for a while to only how me nothing. He told me i should try the dealer (yea right, like the dealer will want to help me out with this) or send it to a manufacture and ask them about it and i guess if they could manufacture one (doubt that too).
SO, after my first try and this i am now thinking of a few other ideas and want some opinions. First off, do you guys have any other places you think i should to try and find something like this? Second, if i were to take a pipe fitting and wrap it around the hanger making it a little tighter but still have play, that this would help a little? I rather stay with a stiffer hanger i can't seem to find one at this point. My search will continue but just looking for some more input from you guys.
Also, there HAS to be more people that haven't voted yet......

Planning on measuring the bracket tomorrow (i'm taking a personal day to get my 10k mile service and a few other errands) for Marcus to see if the cusco one might work and i'm going to try and get a pipe clamp and put that around the rubber hanger. I'll start with it loose and the gradually get a little tighter and see if that helps at all. Just gotta make sure i don't go that tight because of the movement that needs to be present.
Other than that, i have just been really busy so not much time to look more into things. I have another exhust shop i'm going to consult with hopefully this weekend as well.
I will have something to report for ya most likely friday night or saturday

Update SOON!
I have made a few modifications i just need to get the pictures off my dad's camera and post them up. I have some decent ideas that may lead to some possible solutions at least partially.

Slowly but surely....pics!!
Ok guys,
Here is what i have done so far. I first put a 3" pipe fitting around the rubber hanger and tightened it down and took her out for a test drive. It immediately got rid of the rattling noise from the rear, i couldn't hear it anymore but you could still here the vibration from the header cat connection (HCC). I watched it for a few days and saw that it was slightly digging into the hanger, which i didn't like, and it also made the rpm's idle a little higher than before, maybe due to restricting the movement so it won't even idle that low.....strange. However, after a few days, i was driving and i heard metal hitting the ground.....i lost it and it fell off....oh well, 79 cents down the drain. So i then moved to my next and current device which is pictured below.
I did the same thing as before but took a rubber pipe insulator and cut it half so that i cut use the two pieces as protection and additional give on the hanger. I also used a ziptie to hold the bracket in case it falls off it won't loose it again but i will loose the rubber, oh well. It cheap and i'm curious to watch it. The cool part with this is that it is adjustable and you can zero in on how much pressure you want or don't want. Let me show you a picture first so you can get a better idea and then i'll post my observations so far.
So i first put this on and i think it was too tight because not only had the vibration decreased a lot, but i had a little vibration in the break petal and what seemed to be in the engine, like it moved closer to the engine. This is what i was a little afraid of. The engine or the HCC seemed to get a little bit louder since there was less room for it to move. So yesterday i crawled under there and gave it a half turn to loosen it slightly and beleive it or not, the engine was a little quieter and i heard more of the vibration and none in the foot petal. The RPM's in which the vibration occured have changed slightly. At around 680-690 RPM's its relatively smoother now but at around 700 RPM's it a little louder. If i turn off the AC or the heat and just have the lights running, it would slightly vibrate but it does not now. If i turn on the AC/Heat, it will increase the RPM's a little more to where it vibrates a little. I think temperature of the engine and exterior temperature have a lot to do with it as well so i'm curious to see how this fairs in the summber time and when it gets really cold here (its about 35 degrees in the mornings recently, Philly area )
I am curious to here you thoughts, questions, concerns, anything. I want feedback because this is a cheap way to at least help the vibration, by no means a full solution but it did get rid of the rear vibration completely from what i can tell. Again, some of this could be temperature related as well but fire away!
I will continue to update as i fine tune the tightness of the fitting but so far it seems to be holding up very well, even with very spirited driving so far

I think temperature of the engine and exterior temperature have a lot to do with it as well so i'm curious to see how this fairs in the summber time and when it gets really cold here (its about 35 degrees in the mornings recently, Philly area )
I am curious to here you thoughts, questions, concerns, anything. I want feedback because this is a cheap way to at least help the vibration, by no means a full solution but it did get rid of the rear vibration completely from what i can tell. Again, some of this could be temperature related as well but fire away!
I will continue to update as i fine tune the tightness of the fitting but so far it seems to be holding up very well, even with very spirited driving so far
Thanks MacGyver!

It appears that the vibration is a function of the CT header coupled with the engine. My only worry with this is that by strengthening the hanger connection you are transferring the stresses that would normally be absorbed by this connection to some other unknown point which may or may not fatigue quicker.

I was hoping that it would move the vibration backwards and i could keep altering the exhaust sytem to just better damp out the vibration, which is still a viable option but just this way.....as i can tell so far.
However, when my setup does resist the vibration, i don't feel or hear the engine stressing, but that doesn't mean its not, so i need to watch it. That is my goal this weekend.
