I know the type s has better flow than the cl p, so i was wondering if there wud be any benefits in trying the RT cat on the type s.
I know it benefits the preminum alot.
hopefully it does nt mess up ur o2 sensors.

I was stuck between the unichip and the RT cat, moneywise and HP bang 4 buck.
I know the unichip has been desribed as a waste of money by quite a lot of peps on here but so still claim it does add a few HP.
how much ?? is another story entirely.
So what are ur takes on this one.

 

Well what mods do you have currently?

 

I've read on the forums that unichip may provide like 5hp if you're lucky, i've seen the RT cats have gave some people near 10hp but that maybe on the CL-Ps.

 

AEM CAI, comptech headers, (ported)enlarged TB, hks exhaust and running 3 inch pipe to the cat as opposed to the 2.5"
The rest are cosmetic and brake related.

 

What about UR crank pulley? <--very good bang for the buck.
Thermoblock spacers?

The stock exhaust is very free flowing on the type s..

 

yes that the def next one but in addition to that i was split between RT cat and unichip.

So, you dont think the RT will benefit the type-s do u.
i dont know if guys hv gained anything on putting em on the type-s.
its a mildly easy and $$ mods.

 

if u want more hp, i wouldn't get neither. if u want a good mod, the pully is a great mod for the money.

 

Why do you say that? Both have shown to provide mild gains.

 

buy the new apexi neo! the only mod i have is headers and i gained 9hp with the neo

 

well its my opinion. i wouldn't get these first.... if you're looking for power by cost i would get headers, pulleys, spacers, etc. unichip has helped a few, but some say it doesn't do anything so why bother unless you have money to spend right? rt cat, i'd get when you get an exhaust, and even then there are minimal hp gains.

my point is why spend $250 on an intake that gains 3-5hp when u can spend $90 on headers for 20-30hp (numbers are on the top of my head).

 

I would agree that I'd go with the pulley and/or spacers before the UniChip or any high-flow cat. But the UniChip and the cat do produce gains. I picked up about 5-10whp throughout the power band. The increase in area under the curve is greater with the UniChip than with a cold air intake.

 

i have the rt cat on my cl-s and i noticed my car revving up faster and cruises at a lower rpm @ 80mph. i don't know if i gained any power but it def. feels like it revs up quicker than normal.

 

On my 3.2 I went from the 3.0 Accord cat to the RT Accord cat and there was a definite difference especially since the CLS cat flows better stock then the 3.0 Accord cat.

 

i'd like a RT cat sooner or later... lol... sounds like a good mod im just not sure what it does exactly since i haven't looked into it yet.

 

Its supposed to be more free flowing as a result of a drop in cell density from 900 to 350 I believe (not sure, I always forget)

Only problem I have with it is that the size of the flange hole diameter both entry and exit are stock size, so if you have headers and a catback , the piping cross section will be big then get small as it hits the cat and get big again as it leaves, still seams like a bottleneck in performance and I want to test a test pipe on my car and see how it is, but none the less it still helped me, even though it added this ungodly rasp to my exhaust at ~2500rpm under most conditions, its more like a buzz actually.

 

Unless you change the final drive gear or the transmission gearing you will not affect the engine RPM at a given MPH.

 

Hes probably just wearing out his tires more know and noticed the difference in overall gearing

 

unless something else is wrong, i use to be at 3000 rpms when i'm cruising at 80 mph and right after the rt cat i cruise at 2600-2700rpms. what your're saying makes sense tho.

 

Did u hv u transmission replaced ? ( reflashed)

 

Mr steve, <5-10whp>
Is this HP gain just frm the unichip. on NA engine.
i already hv headers, CAI and Exhaust.

 

Correct me if I'm wrong but the stock cat is 900 cell. The RT cat is 300 cell. The gains will be there. I expect somewhere between 7-10 whp. There was a dyno from a long time ago showing something like 10 whp. It was on these forums. It was way back though.

If anyone needs a UNICHP though let me know. I have the software to load programs based on what mods you have. UNICHIP has maps for Injen or AEM CAI, with or without headers, and catback exhaust. And also one for the S/C kit and one for nitrous. It can also be custom tuned and it is plug n play.

 

Yes a custom tuned UniChip gave me 5-10whp from 3,000 RPM to 7,100 RPM

 

where did u get ur unichip tuned and how much?

 

Altered Atmosphere in Gaithersburg. I don't remember exactly how much it was for the tune because UniChip paid for part of it because of some things I was working out for them. I think a tune would cost $250-350.

 

it was me 5 years ago 10hp gain but lost 15# torque another member and I saw the one for the accord then match it up and it fit both of us put them on for two weeks then remove them ,tack times drop almost 2 tenths. had copys of dynos but that was a long time ago.

 

I saw another dyno where one guy 10 whp and made 4-5 ft lbs of tq.

 

So the accord cat is a direct fit for CLS?

I'm looking for a test pipe or hf cat, but want a direct fit.
I see whole bunch of test pipes for accords, but not for us. Anyone know if Accord's test pipe will fit cls?
Or If we share same dimensions in terms of our cats?
Thanks.

im waiting for the extention, but I'll let ppl know how the cat feels

 

Actually most of those test pipes I bet are for the four cylinder applications. Haven't seen any V6 test pipes. I think the dimensions are slightly different at least between the Accords and the type-S models. Supposedly the type S models have shorter cats for less restriction due to the reduction in catalyst I believe, it says the flow more but I remember reading on hondanews before that they were shorter.

Yeah I still have my extension on my stock cat.

 

i have been really wanting to get the RT cat as well but not only cuz i need the HP but also cuz i have no cat at this point and i'm running straight pipe witch sounds retarded.

 

So you have the test pipe with the o2sensor Bung?

Do you have a sound clip?
And if you don't like it, are you willing to sell?

By the way, I just got a shipment of these cats in. $275 shipped for the RT high flow cat, hardware, and 02 extension.
