Good find 'P.S.' and thanks 'RETRO'. I actually read that article in the issue of Modified M'zine a few weeks ago.

 

updated with the latest from HJS

 

I know someone here has mentioned random tech before, not sure how good they are though.

i don't see anything listed for the rx8. I do see stuff for the rx7 though

 

Magnaflow now sells a 49 state legal resonated cat pipe assembly, not cheap either

http://www.magnaflow.com/02catalytic...irectfit=49150

technically neither the Davesport or HJS cats meet EPA legal requirements. They are intended for off-road use only. My own view is any cat that doesn't trip a CEL flag is better than none at all, the EPA be damned.

I googled the p/n. Everybody seems to be selling it for $566.94 USD.
RX8Club also comes up on Google's the first page.

 

wtf-ever ....

 

To clear this up as I just had a phone call asking about it. I checked with my supplier today and they are using the Magnaflow stainless cats. Not sure whom you talked to about the davesport but I dont think we have ever used that, although I havent kept track of which cats they were using and for how long.
Of all the ones we have sold we have only had a couple call about them failing and they were on car running turbos, which if untuned can kill a cat pretty fast.

 

Burns Stainless debuted a new metal cat converter/muffler combination at the PRI show in December, but I haven't seen any specs or other info on it yet

 

I like the way you think!

 

Great thread..thanks for taking the time to put all the info in one place.

I'm trying to decide between the RP supercat and the RX7store cat... who can point me to the more reliable one?

 

hate to say it but don't go with the RP supercat.
I've had two go bad on me...

 

I know its not part of your original 2 but a lot of people are having good results from the davesport cat. Bhr makes a good midpipe that includes this cat.

 

You would have to buy a universal one and weld it into a midpipe.

 

If you want to give me a link to the recommended one for the rx8. I will add it to the list

 

can't say how well it will or won't work/last

http://www.easterncatalytic.com/prod...erformance.php

they also sell an RX-8 specific universal cat (edit: it's the bullet cat linked above) and supposedly are working on a complete RX-8 replacement cat pipe assembly if you search the application guide on the site, maybe an option but I have no direct experience, somebody has to be the guinea pig ....

Info added below

 

What I don't understand is why BHR changed on there site that the Dave sport is not intended for turbo application? Essentially When they didn't have it on the site earlier on?

 

^^IMO it is too small WRT area for rotary NA let alone FI, the HJS cat I have on my NA car is over 5.6" OD, overkill but certainly suitable for 400+ hp FI apps, the HJS motorsport cats now have a Euro5 wash coating that greatly extends emission efficiency life in the high temp range ( 900+ degC) making it the rotary cat converter of choice IMO

I just went through the "hell" of trying to sort out which replacement cat to get. I had a SR motorsport hi flow cat that just fried.... Long story short the name HJS kept coming up, (modified mag rx8 project car, Charles Hill from BHR recommended it, and saw it here) I thought it was going to be difficult to sort out which one to get and thought that I'd have to contact Germany, but it turns out there is an amazing contact in Florida called HJSNA.
http://www.hjsna.com/pages/Contact.html this will get you to the "contact" page... tell them what car and they'll help you get the right model #. I ordered on line and received it within 3 days. The car runs SO much better and even sounds better. Very good experience and very happy with the outcome.

model # info: 9095 0080, $566 w/ free fedex ground shipping in contiental USA.

 

Information added, let me know if there is anything else i should add the HJS section.

 

How did I miss this for the past 7-8 months. Adding the link in my newbie thread and in another thread I'm working on.

Fantastic work.

 

Definately not for a Forced Induction setup, we came up with conclusion the area surface is just way too small.

Some picture of the resonator on BHR mid pipe which is a fair way back stuck with cat material, forgot to take one of the front, but basically blasted the front, and melted remaining.

O2 sensor melted aswell.

On the side note, the pipe is off and we are wielding on a locally produced 3inch inlet 5inch diameter 200cel Euro II Metallic Cat, retail price 350 AUD, got it at trade for 130 AUD :P . Before you worry about 100cel - 200cel nothing gonna get past a EPA (here in australia anyways) and larger surface area in my believes will always be better, then a tiny 100cel surface area. If that does not work, then we will go with a HJS from Germany that will be around 700 aud

 

This is the HJS cat you want for FI; 3" in/out with a 5.67" matrix diameter @ 95% airflow capacity

We gonna see how we go with this cat first, if it works, then saved myself over 1k usd :D

Anyways the cat has gone in, and the remains of daves sport for your viewing pleasures.
