Boy oh boy everyday gets better for the TL. I Finally got the hi-flow cats I have been waiting for, that fit the TL's! (fits Accord V6 and CL V6 also)
See all this hard work is paying off.
I know have this up on the prices page, price is $169, and these are 50 state legal and have Carb #
Been told approx 8 HP gain, but don't have any Dyno #'s to back them up.
Your choose 2" and bolt on yourself or 2 1/4 and get allitle more out of them, and have a shop install the cat and flange.

 

Snook, do a before and after dyno with them. If it does proof that it makes some HP, I am sure alot of people will get them....I know I will

I've heard "rumors" that some V6 people have had problems with the infamous check engine light syndrome after installing a hi-flow cat. Anyone know if there is any truth to this? Once you have everything else upgraded, intake, headers, exhaust, I think the catalytic converter would probably be somewhat of a bottle neck, especially at higher rpms. If you went nitrous, turbo, or super charger I imagine you would really get some nice gains from a hi-flow cat.

 

OK I will go first, and do the Dyno. The O2 sensor is just in the downpipe no ?

 

Sounds great... do u have any pictures for these?

 

i guess +10hp

 

does the catalytic converter increase noise as well?
is it that easy to install?

 

*cough* test pipe *cough*

Cmon wussies, what's with the high flow cat stuff? A real man puts a damn straight through in there. lol. j/k

For real though if a high flow cat works, and there's some way to fool the lambda (cat O2 sensor) then why not go all out?

I was under the impression there is also an O2 sensor near the catylitic converter so the car can "sense" if the emissions coming from the car are within environmental "specs". (Whatever that might be)

A lot of times these things are like urban legends and since nobody ever does it, everyone else is scared to try it.

Fortunately we don't have emissions testing in Louisiana.

 

There is an O2 sensor on the right (passenger side) side of the cat converter!

who makes it tim???.. i remember carlos tellin me this was available a couple weeks ago..

ar

 

how does it affect the tone of the exhaust?
will it be louder?

 

The high flow catalytic converter does not change the sound of your vehicle.
You really should have the cat installed at a local muffler or performance shop.
The warranty is 5 years or 50,000-mile replacement. They are 50 states legal, as well as EPA and CARB approved.
These flow at least 75 CFM (cubic feet per minute) more than any other catalytic converter, I have found
Only one little problem installing a high flow catalytic converter. Legally the vehicle must be 5 years old or have 50,000 miles on the vehicle. The only way to replace the converter before this time is if the stock converter has been removed or been physically damaged leaving it not covered by the factory warranty.
And anyone thinking about removing there Cat all together, it is illegal and you will NOT increased horsepower
ALL newer vehicle that has a computer and/or O2 sensors it will cause the engine to loose all of its low-end horsepower.
Should give our TL's about 8 HP
I am going to contunie to work with the manufacture, of these cats, on my own TL, to make sure we don't have any problems and that the check engine lights won't come on.
Going to do this first, before I put my name on them.

 

actually if you have headers + exhaust, if anything it should decrease the resonance a little bit

 

This is great snook. I'm kind of on budget here, so hearing about $170 mod sounds cool. Let us know how it goes with your car. If it's ok, I'm getting one defenetly.

That's soo awesome to hear....i want one for the car! Thanks for helping us out all the time!

 

so
headers+hi-flo cat+exhaust=should make the headers and exhaust worth it because of this
certain gains!

 

I'm in, if Tim's TL survives. Good luck!

As far as I heard, a Hi-Flow Cat increases low end power, but you actually lose power in the high end.....Not sure about this though.....

I don't think you lose anything with the high-flo cat. I personally have one installed and I love it. I'd prefer to have a test pipe, but we've all talked about this already. It can only help to remove bottlenecks. The only question is, how restrictive is the resonator? Known bottlenecks are: Stock filter, stock headers, cat, and stock exhaust.

 

FYI: some one from the cl fourm put a high flow cat on his type S. and he gained about 10 hp but he LOST 10 lbs of torque in lower rpm. So the lost torque was made up in high end hp.

So does the DYNO prove out the High flow Cat ?

Yes or NO ?

Geez this was posted November last year... any reason we've completely dug up its grave and ressurected it


oh well...

Yeah.

Test pipe.

 

Yeah...maybe you lose bottom end but shoot, just pop in some IK20s into your TL-P and you'll get more torque..

I got the IK20s instead of IK16 plugs in mah car, and they're sweet...

 

f=ma: damn your right i didnt even realize it was posted ever since 11/2000, just the way tim said everything on this post made it look like he had written this lately!(gauges,carbon fiber trims,etc.)

 

i agree with f=ma......test pipe.

Hey Tim will this fit the 1ST GEN TLs also?

 

Did the test come in

 

This thread is from a while back but whats the word on these cats. Im looking to get a new cat but only 2 company to choose from, Random Tech, or Magnaflow. Any suggestions?

 

word..i would like to know also..update?

 

yea after 2yrs, i think its time for an update

 

Which is precisely what we'll be doing, if everyone goes to a test pipe. Cough, cough. I'm not sure why people are compelled to dirty their air for a couple of HP. Literally. Here's a map that helps illustrate the point- http://www.epa.gov/air/clearskies/images/ozone2001.jpg

OBD-II is a mandated engine diagnostic system, that is part of the engine computer. One of the things it has is O2 sensors, both before and after the catalytic converter. The one before the converter is used to control air-fuel ratio in the engine, and the one after is used to monitor the effectiveness of the cat. If it's not working correctly or not present, it will set a trouble code and the check engine light.

Some stuff from the EPA on this- http://www.epa.gov/otaq/cert/factshts/catcvrts.pdf

yeah whats up with that cat story now



@cUr@-TL

 

I found a used hi flow cat for 80 bux but now after searching the posts i see that the check engine light comes on with htese things. i dont want that anoying yellow light on. has anyone had god luck with the high flow cat?

 

I have pulled my front o2 sensor and control the signal to the ecu with the Tech Edge wideband o2 meter. The rear sensor should only need a simple simm,.... being put together as we .....type. My stock cat will remain, but someone is puting together an electric cut-out for the exhaust and may need the o2 simm to keep the ecu happy.
BTW, if I'm not mistaken, our cat has a lifetime warrenty.

 

i would like to have a cat too...
i pretty much beat mine up
i need a new one.....keep me posted please
