NEW T1R 2.5" cat-back exhaust installed--WEIGHT & REVIEW
Well I installed it yesterday.Overall,I'm happy with exhaust, worth th money.Here's just my $0.02.
PROS:
-I like the sound, very deep & throaty,esp at low RPM.
-Butt dyno says improved low-end power & good pull in VTEC.DAMN I wish I had access to a dyno where I live
CONS
minor,maybe just being **** 
)
-exhaust (looking at tip) isn't centered (looks exactly like IO_BURNS install--looking straight ahead at bumper),in comparison to bumper cut-out for exhaust--NO DIGIT CAMERA to sho u guys ; not sure if it's install,design or what.
-stock tip was perfctly centered
-Tip sticks out farther than I thought it would from bumper--almost 1.5"
Not sure if this normal.
-rattling sound occasionally at around 4000rpm
WEIGHT:
I weighed the T1R system on the digital scale at bus depot when I picked it up,so it should be pretty accurate.As for my stock system, I weighed it using bathroom scale at home
with me holding exhaust.
T1R b-pipe & muff= 38.6 lbs.
Stock b-pipe & muff= 60.XX lbs.
---stock axle-back really heavy compared to T1's
Sorry long post,not as wacky/funny as io_burn's post

rattle sounds like it's coming from area near axle-back.Took a look underneath but couldn't see anything wrong.It's rare thing,but just makes u wonder.

Re: NEW T1R 2.5" cat-back exhaust installed--WEIGHT & REVIEW (io_burn)
this is really disappointing to hear. i have been waiting so long for mine, but with all this, not centered in the bumper cutout and a rattle noise...sigh and no one from AJ are responfing to any of my concerns about the exhaust.
its funny but the pics that AJ post of the new t1r is centered in the cutout of the bumper, i dont understand why the rest of yours are not.
did you install yourself or did you have someone do it for you? what cat are you using and what header?

geez art...
shouldn't you have received your exhaust first because you've been waiting the longest? My second one will be here on the 28th...

the not-centered problem should be related to install...i am running a stock b-pipe and the axel backs tip isn't centered after i install my header

a competent muffler shop should be able to correct that misalignement of the tip for you. They'll probably mess with the rubbber hangers a bit to get it to line up properly. But for the cost of the t1 i am a bit dissappointed to hear about rattling.

Re: NEW T1R 2.5" cat-back exhaust installed--WEIGHT & REVIEW (pdcdragon)
for the cost of the t1r, it shouldnt
1)rattle, OR
2)be off-center
installing an exhaust is a straight-forward affair so i doubt its an issue of putting it on wrong. sure, you can take it to a muffler shop and have hangars bent, or rubber hangars replaced, but it should bolt on straight
hope aj is able to resolve this stuff for you guys...

As far as the rattling is concerned, the only time it's enough to notice is when I'm slowly accellerating in 5th gear at low speeds when I'm in traffic and too lazy to downshift. Which again, is no big deal, but you guys are kind of right for a $645 exhaust it should be perfect.

For $650, the exhuast should be designed perfectly. None of you guys are going to say it but i will t1r = 
Why would u want to pay 200+ more for a t1r when you have to bend your hangers for it to align properly when you could of bought a brand name japanese exhuast that bolts right on perfectly the first time w/o rattles?

Re: NEW T1R 2.5" cat-back exhaust installed--WEIGHT & REVIEW (io_burn)
Okay, although I have the OLD T1R, I had rattles as well near the axle back around 3000ish RPM's and when I went over bumps.
Problem- Heat Shields right before the S-pipe (the flange between the S-pipe and the pipe in between the cat and the S-pipe) and the heat shields AROUND the S-pipe.
Solution- Bend the heat shields away from the pipe to stop the rattling. By doing so, my rattling is 100% cured.
As for it being the $$$$ and having rattling, the heat shields have been made to fit around your STOCK exhaust with a smalled ID and OD (i would think), so when you put on your T1R with full 2.5" ID and 2.5"+ OD, of course it will probably bang against your heat shields and rattle. (of course all of this a theory dependent on the stock OD).
mine sticks out straight

Re: NEW T1R 2.5" cat-back exhaust installed--WEIGHT & REVIEW (disordeR)
True, going up a large 2.5" exhaust the heat shield is obviously going to be closer to it no matter what brand it is. I have another brand 2.5" exhaust and while my heatshield wasn't touching I bent it up just in case. The stock heat shield is very flimsy so I could see it really vibrating and hitting things that are close to it. Depending on the condition it's in it may or may not hit the exhaust during engine vibration.

We have made the exhaust hang lower in previous prototypes but the problem then is ground clearance. For a large diameter pipe, there is little room for both worlds.
About the tip sticking out of the bumper, I would like to ask what cat and header are you running? In our installs, the tip was designed to stick at a maximum of 1/2".
The bolts to the flanges can be moved slightly for better fitment of the exhaust, you must play with it. This is actually for ALL exhaust systems even from the largest of companies.
Please let me know if you still can't figure it out.

When we install, we do make sure everything is aligned well. You must do so for any other brand as we have said previously.
Please read my first post and make sure the heat shields have enough clearance when the engine vibrates the most (low RPM high gear).

There is NO bending necessary on any of the installs we have had here.
The brand and quality of the header and cat also have a large effect on where the cat back sits.

Re: NEW T1R 2.5" cat-back exhaust installed--WEIGHT & REVIEW (AJ PwR)
I'm running stock cat and header... When I had mine installed they tried really hard to get it centered without avail, are R Rated and myself the only people to have fitment problems? I think it's kind of odd that his install turned out identical to mine. If so

When I got mine installed at Midas they played with it for a while to get it to line up straight, it pretty much came down to whether or not I wanted them to head up and bend the hangers under the car. I figured if/when I sell the car and want to sell off the T1R and get a stock ITR exhaust back on the car I didn't want to have to deal with un-bending the hangers and inproper fitment of the stock exhaust... So I decided **** it. It's not really a big deal to me, it's not rubbing on anything, but even so it kind of sucks.
As far as the rattling is concerned, the only time it's enough to notice is when I'm slowly accellerating in 5th gear at low speeds when I'm in traffic and too lazy to downshift. Which again, is no big deal, but you guys are kind of right for a $645 exhaust it should be perfect.
Curious how so many concerns on the matter have popped up and AJ Racing hasn't had any comments. *shrug*

Did you try bending the heat shields a bit to get rid of the rattling?

How many 2.5" exahusts from Japan have you installed? How many different brands of exhaust have you installed?
I would like to ask your experience with exhaust systems first as with all exhaust systems we have installed even the top brands from Japan, you have to play with the fitment a bit in order for it to "bolt-on" perfectly.
As we were mentioning before, the exhaust is not rattling. It's because the larger diameter pipes need more clearance from the heat shield. We have had complaints on our first prototypes (which gave a lot of clearance from the chassis) they did not have enough ground clearance.
