Hi- Flow Catalytic Convertor for V6 VTEC
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.

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?

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.

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.

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.

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 ?
Yes or NO ?

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...

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.

BTW, if I'm not mistaken, our cat has a lifetime warrenty.
