ok here we go, the shop i went to - central florida turbo - only gives paper plots, i have high res pics if you want.
my mods on the before dynos =
comptech i/h/e
hondata reflash
they lost my first pass but my second two runs (from a couple months back) were better anyway.
on pass 3 - they hit the stop button too late after they stopped runnung - that's why the hp and tq drop so much (or at least it looks like it does)
also - this is done a mustang style dyno - which like i said earlier - reads lower than a dynojet that everyone else uses.
pass 2:
pass 3 (max hp before)

ok, time for the new passes (the one i did today)
mods added:
hondata intake manifold gasket
random technology high flow cat
believe me - i didn't feel ANY gain w/ the intake manifold gasket - but the difference after installing the high flow cat was almost as dramatic as the hondata reflash itself.
and i know hondata said you couldn't feel the diff with the IMG.
i'm confident to say (thru butt dyno) that the cat made the majority of the 13hp increase.
anyway,i'll elaborate after i post pics.
pass 1 (best pass of today)
pass 2
pass 3 (4th gear pull, the rest were third gear pulls)
this is still better than even my BEST before dyno.

Nice...thanks for the dynos Zee 
Did you notice a loss in low end power at all?
How much louder is the new cat vs. the old cat?
Would this mod make any sense to do if I don't have an exhuast, but have Intake/header?

it's way too late to overlay the dynos, but i'll post best before dyno vs best after dyno so you can see for yourself.
an easy way to look at this is just look at every vertical marker. hp and tq are higher throughout the power band,

i cant tell if there was any loss on low end.
i know my car is happiest once it gets past 4k.
i launched my car today (in the afternoon in 90 degree weather)
i winded out first gear in no time - and after that, it stayed over 5k the whole time. isnt hondata great?
the new cat is a little louder than the high flow cat i bought from jtso (which i will be selling soon)
both cats are noticeable louder than stock. (all my rear passengers tell me so)
if you are worried about loudness, you shouldn't be modifiying the exhuast at all imo.
WOT - my car sounds like a s2k.

once i find out if i will get that much power even if i dont have hondata and an aftermarket header, i may then be putting my jdm pedals on hold but if i wont them i will get the jdm pedals now and do hondata, header, and this at the same talk about a super power increase.

IMO you won't get the same power without the hondata, I/H. You need these parts for the car to bread better. Hondata ECU is on a level of its own, with this ur car does wonders. Now we have Random Cat to complete the puzzle. Can't wait to add this and feel my gains

no. it's in my opinion that you would need the whole setup (i/h/e) to see those gains.
i always use the straw analogy.
if any point in a straw is bigger than another you cant blow through it faster. you'll always have a choke point.
on the other hand, if the straw is bigger all the way through - you'll be able to push more air through.
i dont know though - i'm def not an expert on this subject.
i would ask clay at random technologty and see what he thinks.

these guys def know what they are doin though.
they use their dyno to create 500+hp civic's.
in fact, their civic ran 10.4 @1xx in the 1/4.
they have videos.
just google central florida turbo

I was about to ask the same question since I have a CAI only. Then I relized that this was only one day after the very first dyno was run on this product. Until someone gets further tests done about the following, its all speculative:
- stock TSX
- w/ intake only
- w/ header only
- w/ i/h
- w/ i/h/e
- i/h/e + hondata
- hondata only
- low end power decrease
You get the point. In time, we'll have the answer for every setup out there. Thanks to guys like Dzuy for taking one for the team and sharing the info.

Do you guys think I would still see the same gains if i have Hondata, intake, and headers, but no exhuast?
Since the exhuast only adds 1-2 HP, I'm guessing that the TSX exhuast is pretty non-restrictive. What do you guys think?
...Damn the only thing keeping me from doing this mod is that I probably won't pass smog here in Cali with it on. I'd have to take it off whenever I needed a smog check.

I am in the same boat, but I am going to go ahead and get the cat, at worst you would only see like a 10hp gain as the improvment on most of the after market exhaust is pretty minimual.

Atleast to me it looks like this CAT has completely changed the power band of the car. I mean there is no drop off any more but instead a constant increae in HP. also the torque band now goes almost level the entire way. And last it looks like we get low end power quicker. Now being that i really know nothing about engines that is just my observation from the two graphs

I'll just wait a while after I get the cat to get the Comptech header and do it once. I just know I'd be that guy who scratches/cracks the ceramic off the header and has a leak in a few years.... being in the salt belt part of the country, you have to be very mindful of rust.
