Davesport 100cpi metal core high flow cat

A couple of RX-8 owners who autocross/track their cars have expressed an interest in this product. Dave @ Davesport needs at least 5-6 people who are willing to buy one before he'll order another batch from his supplier.

Product description from the Davesport website follows:
Exhaust : Performance Metal Core Catalytic Converter, 100cpi



The Davesport metal core catalytic converter is an extremely durable, high flow catalytic converter ideal for race and rally cars, off road vehicles, or any application needing a high flow, longer lasting cat that can take a abuse! These cats hold up to extended anti-lag on race cars, so they'll hold up to anything! Specify exhaust tubing size. This is a 100 cpi cat suitable for race cars.

These cats feature a 4" diameter round configuration and have the following features:
  • 304 Stainless Steel case
  • Quicker "light off"
  • 15%-30% Less pressure drop than a ceramic of the same size
  • Reduction of overall size
  • No matting required
  • Higher thermal shock resistance
Link: http://www.davesport.com/cgi-bin/davesport/DCAT100.html

Forum member swoope has runs this high-flow cat on his car and there is a discussion of it in this thread: https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/hi-flow-cat-buy-not-pipe-cat-just-cat-136242/

If interested, please vote in the poll and send a pm to forum member Mr. Pockets who's communicating with Dave @ Davesport.

P.S. From the Davesport website, the price listed for this cat is $138.

Also, for those that might be wondering, this cat could be paired with a pre-built catless midpipe, such as the one with 3" tubing that rx7store.net sells for $199 on their site (has a pre-welded O2 sensor bung):

To be honest, I can't provide any more detail than what Chike has very graciously posted. Thanks a lot, dude!

I, personally, will not be collecting any money. I just want a list of interested parties as a first step. I have no idea how long it will take Dave to place the order, receive the product and distribute it. I wouldn't assume it'll be any quicker than a few weeks.

I was the one that originally found this cat. I had sent off an email to them and this is the reply I received.

Hello Allen,

I've actually sold several to rotary guys. I unfortunately have no additional facts on the cats. The manufacturer doesn't provide them. I can tell you anecdotally that my rally customers are getting several seasons on them using full anti-lag, which also raises exhaust temperatures to ridiculous levels. The farther back you can place the cat the better though - both for flow and for longevity.

Best regards,

So far, Swoope is the only one that I know of that has tried this cat and he has had no problems so far. I found one of another brand real cheap, so I'm not using this one yet.

Al,

Thanks for your input. Hopefully swoope can add his $0.02 as well.

Good news!

Dave has ordered the cats. He should get them in the next 7-10 days. Feel free to place the order via the Davesport website. No need to PM me or take part in any sort of poll.

I've used this cat on my FD, it has worked for a number of years but I don't drive the car all that much.

I'd be curious as to who is the original manufacture of these cats.

It looks a lot like the car-sound (Magnaflow) cat that we used on our RallyCross car.

I did a lot of searching on the nets last night and came up with nothing. I think to find these, you would need to go SEMA or the other performance show in Indianapolis (I don't remember the name of). There is probably a small booth manned by one guy thats pushing these no-name cats.
On the nets, I found a lot of references to 100 cpi cats, but I couldn't put a name to them (in North America). Davesport is the only company I found that was actually selling them. Even finding the 200 cpi cats wasn't easy.

You have to overlook overseas.

I have found plenty.

On my assumptions, if these were made in the USA there would be no hesitation to get these made becasue they could be quickly made and shipped.

They could be imported from either Europe/China/Japan and so forth.


This is from 20+ hours of searching and researching.
