Ok so im planning on getting the atlp j pipe and was wondering about the type s cats. I considered the pro cats but not after reading the bad things about them. So i talked to the dealer and the two cats on the manifold are like 900 from them. They also said that i may need the new o2 sensors also because it is a different part number than for the 2005 tl. Do you guys think that my current 02 sensors will work or do i need the new ones? Do you think i will even notice a difference in power with the new cats? If so were would be a cheaper place to get them? I looked a oemacuraparts.com but they dont list anything for a type s just a regular tl. Or should i wait for atlp to come out with something?

the type s cats are less restrictive then regular 04-06 cats.

 

I would wait to see whats gonna happen, because maybe Mike will make some pro-cats instead of just test pipes because we do drive TL's not riced out civics and kinda need to keep our O2 sensors and cats on the car (3rd get rid of it ).

I would do some basic reading as well on the internet i think the type-s cats are 600 cel and base 04-06 are 1200 i believe I would confirm this but do some reading to find out how much power you could possibly get from swapping them out cause no one has done pre post dyno with type-s cats on here, maybe there is another car forum that has pre post dynos for higher flowing cats.

Now if you are really nutz (cause I am not going to do this) you can wait for the test pipes/headers w/e ,you want to call them, that will be catless and get those but then your tl will be having stinky exhaust gases coming out the back of your car and youll be polluting a lot more then you should be.

 

For $900, I don't think it is worth it, imho. The eshift cats get you about 20 hp, and the type s cats should give less gain. I am also thinking that the type s hp gain is about 28, and most of that has to be from the increase in displacement (3.2 vs 3.5 liter). At around $500 I might think about it.

 

Yeah just wait until people start getting the test pipes and then you will see people selling their type-s cats on the black market and youll be able to pick up a cheap pair and then it will be worth it for sure. lets say you get 10 hp from them well then its worth 400-500 bucks for sure just like the j-pipe.

And I just noticed the thread about richies test pipes and you are going to have enough people doing this that you should find someone selling their type-s cats.

Just keep a look out because I know type-s cats will sell very fast on the forum.

 

I doubt alot of people will be selling the type s cats just because the offroad cat deletes are going to be released...

I swapped my type s cats and sold them to cover the expense of the procats... which was shortly before they began to fail... by which point in time the interest for type s cats began to build... I wish I had a chance to compare the inside of the cats and see if they truly were different than that of the base cats

ps. YOU DO NOT NEED NEW o2 SENSORS... I've been rolling on procats 4 months + and I am using the sensor that came with the type s... which means the o2 bungs are identical diameter

 

Ok i guess ill wait. Its no rush anyway. If anybody wants like 500 for their type s cats ill buy them if not ill wait for something else to come out.

um they are $600 and change new... just thought you should know

front: 18190-RYE-A00 --- $320
rear: 18290-RYE-A00 ---- $330


3rd cat COMPLETELY OPTIONAL AND UNNECESSARY

 

Al,
Lemme make you feel better.

I compared my stock 06 cats to the 07 TL-S cats, and visually couldn't tell a difference... of course, comparing 1100 cells/inch to 900 cells/inch takes a bit of a magnifying glass to discriminate. I think they're different, and better flowing, but visually, you'd never know... again, recognize, the TL-S exhaust is advertised at 14% better flowing, so I'd likely believe the cats compose most of this... but how much more power is 14% better flow. Likely not much. I'm hoping to compenate with ATLP Jpipe and exhaust...
Rememebr too guys, ya gotta have some backpressure if you're NA.

I sold my procats because I was displeased with the build quality of the cat (some the worst welding I've ever seen, and mild sttel flanges that were already rusty - the horror ). The recent premature failure stories were enough to push me over the edge. I'm about to Supercharge, and don't want to have to replace the cats in 10K miles...

The real answer is somewhere in the middle. Most of the smart guys here say the ULEV tuning causes the car to run crazy rich when cold, to light off the cats faster... but this burns up the smaller procats substrate. Others says there's a known batch of bad pro-cast in circulation. Others say running meth causes them to fail...

There are reports on both sides of the fence on all three accounts... MugenR has 20K problem free miles, blown, running meth. Blacura had a problem in less then 10k miles, naturally aspirated...
Either way, there was too much risk, with too little return for liking.

I will say this, the cats I removed and sold to DanK looked as good as the day I installed them (shitty welds and all). There didn't appear to be any cell degradation or shrinking... even after 20K miles. I frankly believe the failures are genuinely a defect in the metal cat substrate.

Given the way you drive, you'll know real soon if you're gonna have a problem.

Offroad cat is terrible idea in my mind. Terrible for the environment, won;t create much more power than the pro cats, and you're gonna have a cel problem without a full retune... it's that simple.

 

why not save yourself money, take the cat out and drill out a bit of the cat, that should provide a freer flowing cat, while retaining certification during inspections.

 

It's a ceramic,/metal honeycomb... You can't just "drill some of it" out.

 

don't tell kennedy to drill out a cat.... he'll



not but seriously that is a waste of money to drill out the stock cats... those are not cheap cats
