I just received the following e-mail from Dave at Random Technology:

"As it turns out, we had a converter to fit the 2000-2001 models all along. It's part number 822530 and it's the same one that fits the 99 models. Thanks to your efforts, a local Maxima owner contacted us and brought his car in for us to do a trial installation. We installed our part number 822530 and it fit beautifully. We haven't had an opportunity to do a comparative dyno test, but we should be able to get to that in the next few weeks."

Go get 'em!

hey y2kse that person that let him use their car was me.... he also said that he wants to use my car for a cat back system and front strut tower brace as well...... glad to hear that u r excited about this .... i was ..... and cant wait till i hit the dyno before and after the cat back system i will let u know more when i do ... later

Good going to the both of you... now we need dyno numbers.

Let me be the first to thank you for taking your car in for a fitment. I suspect a lot of 5th Gen owners will be grateful for your efforts even if they don't say so out loud.

WILLSE

anytime!! i really cant wait to be the first with the RT cat back on my car it should be just as good as stillen..... the numbers on the dyno should be good but the mods that i have done: stillen hi-flow, stillen y-pipe, "RT high flow cat", stillen crank shaft pulley: should give it a better turn out........hoping to get a good gain from the cat back... maybe i can break 260 at the engine.... i dont believe all of the numbers that stillen gives me for the estimated hp gain........ have to see on the print out sheet.... might buy a g-tech pro to get a basic idea of what is at the wheel so either way wether i dyno it or g-tech pro it i will post the results.... hope for it to be as good as i expect

MrBurner

how much do these usually cost and what exactly do they add? hp/torque/noise wise

I saw a group deal recently that indicated about $160.00 for the cat. As far as results are concerned, check out the following:

MrBurner

wow, it makes that big of a difference? so if i get a full mandrel bent exhaust w/ free flowing muffler, y-pipe, hi flow cat, and CAI i should be looking at around (175+5+15+10+10=) 210-215hp to the wheels? w/my stock exhaust setup and this what is the estimated gain? $160 sounds like a great deal...does this just basically replace the catalyt converter (sp?)?

Y2KevSE

210? Check out madmax2k's dyno number... 203 fwhp with y pipe and CAI and his stock dyno was 190. The RT cat should not give 10 hp's at the wheels... So with all those mods on an auto, looks for somewhere in the 190 range (probably less).

Yes, it replaces the main cat.

MrBurner

kev, w/o any other mods what should the new cat give you? will it make the exhaust louder?

WILLSE or anybody who goes by the shop,
Can you find out if they sell direct to the public from their shop? I know they sold it to you at X price, but you were their test specimen. I was thinking about just going by their shop (note: I live in Atlanta). Would the price be the same if I went by there vs ordering from an online retailer, per se? I suppose I could just call them, too.

WILLSE

if you have a y-pipe and high flow cat, with a cat back it will be louder than if u just had the cat back........ more air flow ...... if u put a high flow cat on a bone stock max RT said that they pushed 8-10 extra at the wheel of a 4th gen when they dyno'ed it so i guess it should be the same if not more because more air flow is running through the 222hp engine to the 190hp engine so somewhere around there if they quoted me right.... when i dyno it which hopefully will be soon i will post the results and let you know what all of my mods add up to at the wheel.....

so open, I would hope to see improvements but I think some one dropped their exhaust and back on a dyno and got almost n gains. But I hope to be corrected once they dyno.

Dave B

No, the RT cat doesn't add the power they say it does. My 4th gen Max is making 176fwhp/193fwtq with the OSCAI, B-pipe, RT cat, and Y-pipe. When I added my RT cat, the gain, if any, was hardily noticeable. I noticed a lot more hp and torque with the B-pipe.

Dave

punkdork

WOOHOO another OSCAI convert... 4th gen too!

Y2KevSE

As Dave B said, it'll probably not give that much at the wheels. From what I've read in these forums, the RT Cat added around 3 hps. I highly doubt it'll be 8+ for us, but we'll soon find out when WILLSE dynos his car.

Wustylez

Does anyone know that if RT has fixed the leaking problem I heard some time ago??Or it doesn't apply to 5th gen max?

So anxious to see the Dyno number too.....

got rice?

<I>Does anyone know that if RT has fixed the leaking problem I heard some time ago??Or it doesn't apply to 5th gen max?</I>

as long as it's installed correctly, it shouldn't be a problem.

MrBurner

WILL, any update on this? have you gotten it installed yet?

y2kse

<B>DO NOT FOLLOW THE INSTALLATION INSTRUCTIONS PROVIDED WITH THE CAT!</B>

The instructions indicate that the cat should be installed so that, when laying under thc vehicle with your feet out the rear, you can read the numbering stamped into the cat. If you can read the numbering stamped into the cat, you just installed your cat upside down. Start over.

To install the cat correctly, look for an arrow marked "FLOW" on the side of the cat. Install the cat using this arrow as a guide. And make certain the heat shield is on the bottom, not on the top.

I've learned never to believe what any manufacturer says about power gains. For instance, let's say that you replace a stock catalytic converter with 50,000 miles on it with a brand new stock converter. Will you realize a power gain? Probably. Now let's say you replace the used stock converter with a new high flow converter. Will you realize even more of a power gain? Probably.

So the test that really needs to be run to properly compare apples-to-apples is a NEW stock converter versus a NEW high flow converter. Has anyone including Random Technology run such a test? Probably not.

Having said that, I DO notice a little better throttle response with the RT cat installed. I also notice a little more exhaust drone in the cabin.
