Default Who can recommend a TBE with high-flow cats (to keep it legal)?

I'd prefer a full up/mid/down pipe setup to minimize installation headaches... I'm an auto-noob. New headlights and audio is the extent of my experience to this point.

Thanks!

And remember, it's gotta be legal!

You can't replace your stock cats legally for a number of years.


That said, do you want to have 1 high flow cat in the system or do you want to replace each stock cat with a high flow one?

Random technology makes the only full exhaust that I know of that retains 3 high flow cats. Technically even that sway is illegal according to Federal laws.

I have the random technology uppipe, downpipe, and midpipe with all three high flow cats. Awesome power, honestly, I think its better than catless ( my opinion ). Anyway, i have three certificates from the EPA with a serial number and phone number. I keep this in my glove box just in case pigs pull me over. I STRONGLY reccomend their product ( if you have the money ). It will save you the pain in the ass about switching exhausts if you are worried about passing inspections. But to answer your question, yes, its legal and I would go for it if i were you. My opinion- just get a catless uppipe if you want a little more power.

I have the random tech downpipe (w/o cat) and the midpipe (w/ cat). It was just something I was looking for at the time. I wanted the cat to be father back from the turbo as possible. I think I should be able to pass emissions, but we'll see.

i have TXS stealthback w/ one hi flow cat and STi axle back.
its legal and i passed emissions.

u may not want a cat in the up pipe and a easy fix to that is the the USDM STi up pipe which is OE and catless.

One needs to define legal to get an honest answer here. If you remove 2 cats and still pass your local emissions test, are you legal? Yes, according to your emissions test....No, according to federal law. State laws also apply, but one cannot discuss the laws of every state in one post. Section 203 of the Clean Air Act covers emissions modifications in legal detail for those with interest. You also have to look at your state laws as well.

Needless to say if you remove, gut, tamper, or do anything to your emissions control items in your car, YOU ARE ILLEGAL! Obviously, if you have EPA certs to back you up, this isn't true, but Random Technologies is the only company I have heard of that goes to this trouble.

I have a catless exhaust, so don't call me a treehugger, just stating fact.

Only after 80,000 miles is it legal to replace your cats on your vehicle. It used to be 50,000 miles, but changed a couple years ago.

But to pass emission testing (not visual inspection) one cat may work.

Ok, very comprehensive people... thanks.

Looks like cat-back and a stage 1 reflash might be in my future. Maybe I'm going to have to quit being such a wuss and think about a new turbo and injectors then.

And of course there are the suspension mods.

I may go with 17x7s and new springs when it's time to get rid of the OEM tires.

Boricua Racer,
Did the random unit come with the EPA certs? If not, how did you go about obtaining them?

You're only going to be legal via the sniffer with cats not visually. If you are paranoid about all this, just find an inspection place that cares about passing and not visuals...that's what I do.

In some parts of Texas all we get is an OBDII test... No Codes = Passed test. So it's all about who you know and where to go.

At first I wasn't going to go catless as my other vehicles still have them, but I know where to go if need be to "pass" the visual so it's really up to you what you decide.

Yes, they came in the box with the exhaust. It has a serial number as well as a phone number to call, just in case you need to show a cop.

Unfortunately even random acknowledges the 50,000 mile rule. From their web site:

Under Federal EPA regulation, replacement of original catalytic converters is allowed only if the original converter(s) is missing, or the vehicle has more than 50,000 miles or is at least five years old and the need for a replacement has been established and documented, or a local inspection program has determined the existing converter is in need of replacement.

So even with CARB stickers and EPA certificates if your car has less than 50,000 you are in violation of federal law - doesn't matter what your local laws are.

MRT 3" turbo back. It comes in single tip or double tip. I am running this setup and it comes with 1 high flow cat in the downpipe. I would think this will pass emissions, but I haven't had to test it yet. It's an awesome system but a little on the quiet side. The sound is still nice though...more like a mellow rumble. Fitment is awesome and the installation is easy. I would highly recommend this turbo back.

Definately not legal - you have removed at least 1 cat.

It's not legal, but it will pass emissions. I've read posts of people have this same setup and still passed emissions.

People have passed emissions w/ just a single high-flow cat in the turboback. Personally I would not want a high-flow cat in my uppipe. I don't know that the high flows are quite as diesel as the OE ones, as far as longevity, and as such I'm not sure I'd want one before the turbo

^-- speculation

The uppipe cat is mostly for cold start emissions. The main cat is the last cat. You would probably have trouble passing with just the stock uppipe cat in the system (espeically if they do a visual test). Many people have reported just passing a sniffer test with a variety of systems with just 1 cat. However, the issue here is that you are still in violation of federal law.

This is true, but some people make it sound like the uppipe cat does nothing after it warms up. Not true. When a cat is too cold it doesn't work. When it warms up, it starts working and keeps on working. If it gets too hot, it melts.

Talking with some engine experts around here, they speculate that the uppipe catalyst is an oxidation catalyst only (HC and CO) while the downpipe and third catalyst are probably three-way catalysts (HC, CO, and NOx).

I live in OK, and we got rid of annual car inspections. So I dont have to worry about that, but my question is does a TBE with just one high flow cat smell funky? Cuz I have smelled cars with broken cat's and they smell like rotten eggs. Also if I only had one cat and ot pulled over would a police officer ever check to see if I had all of mine? Basically I want to know what the dangers of getting a TBE system are if I do not have to worry about annual inspections!! Thanks
