Random Tech High Flow and Temp Cat
 

I dropped my car off today at Random Technologies in Atlanta, GA for them to design and install a prototype high flow catalytic converter. I am doing this in hopes of running a cat with the stage 2 'zoomer mod. I would rather run clean here in downtown Atlanta than just run a mid-pipe. I stayed there while they removed my old cat and began to design the new one.
They are going to make a prototype by hand bending everything, test fit it, build a jig for producing them, and finally build and test fit another one on my car. This means that after they have produced mine, they should be able to easily produce the setup for anyone interested.
I forgot to mention that this replacement will be bolt-on so that I can swap the cats for service or emissions. I will not, however, have to fool the 2nd O2 sensor like you have to with a mid-pipe. The major benefit of using a Random Tech cat is that it should be able to withstand the extra heat generated by the stage 2 mod. I believe Maurice is already doing some testing with a cat he got from Random Tech, but no updates have been posted about that. I am sure he is still busy with getting Stage 1 out the door.
I am hoping to do some Dyno runs after the new setup is installed to see what the car produces with a Borla and high-flow cat.

Great! Keep us informed on the progress. :D

Yes Xavier, please keep us posted. I'm interested in doing the same thing. You might want to email Maurice (maurice@harddata.com) with what you're doing... I suspect you may be saving him a lot of leg work.

I connected with Dave at Random Tech through Maurice originally, so he is aware of this development. I have just emailed him with an update. Random Tech has already sent a High-Temp cat (only the cat, not the mid-pipe with cat installed)up to Canada for testing, but as far as I know there has been no update on it.

You are the man! Hopefully itll be out soon so i dont have to run straight pipe!

Re: Random Tech High Flow and Temp Cat
 

The 2nd O2 sensor may still need to be fooled, because most high-flow cats, by their design, will not provide the same level of O2 your current cat does.

I think the sensors are pretty simple, easy to fool.

yes all you usually need is some tiny resistor in order to fool an 02 sensor :)

After hearing some concerns about tripping a CEL, I gave Dave at Random Tech a quick call, and everything is just peachy. They may not have the car ready till Thursday, but if we do trip a light, he has all the equipment needed to fix the problem. I am ofcourse hoping the car doesn't have a problem with the converter, since Dave said many cars don't, but their is no guarantee of that ofcourse. Just have to wait and see.

Did talk to Maurice via email last night, and a sister cat to mine goes on his car next week. He is suggesting I try a Stage 1 mod with the high flow and Borla before upgrading to Stage 2 since it seems the exhaust mods greatly enhance the Stage 1 upgrade. We shall see. I am greatly looking foreward to seeing what the exhaust combo will do on the Dyno.

Well, after a few issues with a broken pipe bender at Random, I have gotten my car back, complete with new high-flow cat. I do have to warn everyone, without the stock cat and resonator, it is louder. Not unbearable, but louder, especially with the Borla. Still nice and deep. My car does have a prototype on it, which will probably be switched with a production version when they are ready. In the mean time I will be evaluating the performance, sound, and testing to see if I get a CEL.
The protoype is very good looking, with nice smooth bends. Dave has told me to give the car a few days and decide whether it needs a resonator to quiet things down a bit. The mid-pipe is 3 inch tubing the whole length, and uses a very small looking, but effective, high flow random cat. I asked a few questions on behalf of fellow forum members, and found out the production version should start shipping in Mid January, depending on the success of the prototype and whether it needs a resonator. When I get the first production version, the car will then be dynod with Cat and Borla. I am hoping to do a base run with Borla and one with high-flow cat and borla, but we will have to see. As soon as I get them, I will post them.
Anyone in the atlanta area interested is welcome to see/hear the combination. Also, if anyone has the equipment to do a sound clip, I am sure some people would like to hear it. Glad to answer any questions.

This is something that I too would like to do in addition to the stage 1 and a new exhaust. Even though we dont have emissions here in FL I would like to run legally and still get as much as can out of the car. Of course like all the rest I await with baited breath any new tests/developments.

Xavier, do you have access to a digital camcorder? That would do a nice job of recording the sound with the new cat + Borla (which would be the same as my setup :D). Also curious as to the price Random is thinking of charging for this unit, if it is a bolt-on, and if they will be providing new O2 sensors to prevent CELs. Thanks...

No price yet. Bolt-on. 100 miles so far with no CEL. I am hoping it stays off, but only miles will tell.
I do not have a digital camcorder, probably a few digital pics is the best I can produce. I will do that when the car is on the lift getting a production version soon.

Yes, pics would be good. Also would bet that Random would have the capability of making a sound clip available. Just a thought.

Still curious though... are you using the stock O2 sensors?

i just wanted to say ditto lol!

500 Miles and No CEL! Very happy. Update from Random soon.

Been reading alot of negatives on random tech.I think I will get a carsound.Im more comfortable with them since i had one on my supra.4 years of kicking the hell out of it and it never failed.

Care to share what negatives you've heard? Just need to be informed.

How about an update, Xavier296? Thanks...

Finally, an update. Haven't seen Dave over at Random in awhile, as holidays and other circumstances have prevented it. Per my request he is building a new prototype with a resonator since I believe without it the car attracts to much negative attention. I DID end up throwing a CEL, and we are going to work on that this week or early next week. May be loose connections or flanges, not converter efficiency. We shall see.
No dyno. Have been advised against till I can find a dyno operator nice enough to let me unhook the rear ABS units while hooked up. I really want to dyno, especially with/without CZ stage 1. I believe my exhaust setup will yield large gains with the better fuel maps. I will update again after I make it up to Random again.

Cool. Please keep us posted.

Hey Xavier, any update?
