Hey guys, what high flow cat do you recommend? Im looking for something that will have a deep sound when used with the racing beat exhausts. I would go catless but I really dont want to deal with a CEL right now. I also want something that will pop a few flames because thats cool lol. Please share your experiences, im sure many people will benefit from this.

RP supercat. I have it with my Racing Beat exhaust and it sounds awesome!!! (check youtube, there's soundclips from other members)

Not sure if the supercat will pop flames, catless will. Also with catless the smell is pretty extreme. RP is good, I hear you can expect a whopping 5hp from it but hey, no cel, no smell, good sound, and better flowing exhaust.

I have a midpipe and Im very happy with it. Lots of flames, it loud with the stock catback, and I got some power out of it.

Hopefully something I said helped....

Weird though, somebody on this forum was selling a Supercat that displayed the CEL.

wouldnt surprise me, a lot more air flow. :lol:

Never had a CEL light with my RP unit. Worked like factory stock. Made the RB exhaust sound real nice. Not too over bearing, which in hearing some 8's with the midpipe I thought they sounded way, WAY too loud.

i've shot flames with the supercat :wiggle:

thanks guys, supercat it is. Also ill be installing the Greddy turbo kit in september, will I still have fire making capabilities lol?

don't get the greddy. (requires a LOT of work to get it to run properly)

Look at the Esmeril kit for sale right now by NgoRX8, it's priced close to $1k below standard price.

I just installed a used RP Supercat this past weekend. Super easy install (with guidance from my dad, the uber mechanic). I was also able to reuse the front gasket and rear seal. Sound is definitely more aggresive, even with stock exhaust and intake...I don't know about flames though. I have only been running for about 100 miles, but as of now, there are no CELs.

I'm really looking forward to getting a MS Exhaust (Ver. 2) and MS CAI this coming weekend. I hope it sounds great and won't be too ricey.

keep in mind i don't shoot flames like a catless pipe would. you have to try harder with the high flow, get her nice and hot and keep the revs really high. it happens for me when i shift at 9k but it may be different for everyone. if you want instant flame action then you need the catless pipe

Is the smell with a catless really as disgusting as some people say? Also is their a cheap way to turn the cel light off other than buying a accessport? If the catless is going to give me more power once the turbo is installed then ill probably just order that and the catback from racing beat.

i have the rp supercat, nice people on the phone but ive had my issues with them, if i could do it again id go for the mazsport dual resonated midpipe but u will most likely get a cel with that...

i use the rp supercat. been having it for about a month now. with the mazdaspeed exhaust it sounds great and havent had an issue yet. there is a new version of the supercat. here is the email they sent regaurding the new cat verses the old.

"You are correct that the new V2 converter is different than the one in the picture. The original RP SuperCat had a smaller metallic substrate converter. It flowed well, passed emissions testing, but had a tendency to distort if temperature parameters were exceeded. We went to a custom made ceramic unit which has slightly more flow and far higher temperature ratings. We went to this type converter about a year ago and have had no failures or issues. Hope you enjoy the product and feel free to contact us with any further questions. Thanks"

quick question-

is the RP supercat and the B&B catback compatible?

Any catback should be compatible with the RP Supercat. It tapers down in the rear to meet up with the stock exhaust so anything that is compatible with stock cat should work fine with the Supercat.

Also, I have the RP supercat and RB Rev8 and they sound awesome together!! Going on 10k miles with them and no CEL.

you WILL get a cel from it.

I have the MS dual exhaust and supercat combo. I like the sound.

Yeah, it's nasty. Have you ever pumped gas and accidently spilled some & you reek of gasoline. It's like that. And no, there really isn't a fool proof cheap way of turning off the CEL light. OBD is doing what it is supposed to do, detecting that there is no catalytic there. For the marginal hp gain you would get froma testpipe vs. a hi-flow cat the tradeoffs are not worth it.

No cat is freakin' nasty. When you stop at a redlight with the windows down, you will be inhaling some strong odors. If you get (mid-pipe), save it for race days. Get a hi-flow for regular DD.

okay, I have an RP midpipe and I use my 8 as a DD. It smells like an old school muscle car, theyre exhaust fumes. Yes with the windows down you will smell it but its not bad. With the windows up I have yet to smell an exhaust fume.

$160 installed for flames at will and more power = worthwhile mod.

PS- I have a VERY EASY fix to the cel you will get. Find a really hot wallet size picture of your girlfriend and put it there, no one will ever know/see the cel behind the picture. Im serious.

:lol: :lol: I shouldve thought of that, you are truly the man. Im thinking the rp high flow is the way to go. Ill probably go with the esmeril kit too because from what I can see its the best bang for the buck plus the bragging rights you get with a T-70. I know this is changing the topic but does anyone have experience with the dash guage pod from rx8strakes? Im looking for something that can pass as stock.

Well, that's your opinion. For some "old school muscle car" smell = stinky tailpipe. Maybe I'm older now, or maybe I think my $34,000 car shouldn't smell like a $500 hooptie and I don't want to ghetto out my car with pictures everywhere & junk in my car. You can do what you like with your car. I have my opinion, you have yours.

PS gtballa, you should check out Mazdamaniac's turbo kit as well. Essentially a Greddy kit, but with the problems fixed & much larger turbo.

huh, didnt realize a wallet size picture of my girlfriend was ghetto:lol2:

My car smells like peachy peach when my windows are up.

So, your opinion is fine, just incorrect. :squint:

Whatever, like I said, people are entitled to their opinions.

gtballa, you've seen some people in the post describe what it's like with a midpipe (smelling like a gas station). I guess if you want to drive your car with the windows rolled up all the time, your car can smell peachy, I guess.

what turbo does the greddy kit come with? the only thing I know is that it isn't as big as the t-70 that comes with the esmeril

haven't smelled very many gas stations that smell like a midpipe.

Drive up to a gas station & pour some gasoline on your shirt and voila.

Whatever internet tough guy. Calling me a pussy through a message board because I think a car with no cat smells like ass. :uhh: Maybe your just a short, short man that wants to pretend that he's got a cool car because it smells like a POS car of the 60's. You're trying to talk trash because I gave an opinion that I didn't like the smell. Guess what, some people don't like the smell of a catless car. Just because you have one, doesn't mean you're cool guy that is right. How about just STFU. I you like it that's cool, but don't call my opinions "false" or "incorrect." They are as right as yours genius :spank: . You're not being a smartass, you're just being an ass.

PS, the 21st century called, they said you don't have to have a car that smells like crap when you open a window, you don't have to have an CEL light on all the time, and you don't need to piss everyone off in the neighborhood for about 2 hp. If you think you get more than 2-3 hp more from a midpipe than a supercat, then you are delusional.

Nope, Im actually 6'5''.

You just need to take it down a notch, no need to get your panties in a bundle.

Actually, you generally get 2-3 from the supercat, or 5-8 from the midpipe, so Im delusional.

Hey, the 21st century called to let you know that you dont have to cry because someone disagrees with your overdramatic statements. My last post was actually a joke, hence the 'grouphug' smilie, just screwing around. Figured a member with 3000+ posts would just laugh it off and realize were argueing over the way our cars should smell.

With that said, chill.

Then just apologize, & move on. If you make cracks on a guy, then expect it back in spades. I figure someone with over a 1,000 posts on here would figure that out. Your jokes can be construed as insulting, & hence you get it back.

And BTW, the hp for an RP Supercat is about 5-6 hp (See Nemesis posting), and the midpipe a little more than that. Dynoed on this board (not the 2-3 that you claim).

what turbo does the greddy kit come with? the only thing I know is that it isn't as big as the t-70 that comes with the esmeril

They call it a T618Z, which is basically a TD06-18G. The Mazda Maniac upgraded kit comes with a much nicer modified Garrett GT3071R.

Hello

i´m From germany
Who can i order the RP supercat?
i found it only on www.rx7.com but nobody answered my email request???

Greez Stefan

Hey Stefan, i'm in europe too (Italy) and we found, after some research, some european producers that have "non melting\gutting" catalyzers for our car.
If you need a catalyzer i might give you their email address.

hmm
but i want a RP supercat :(

Greez

A dyno before and after the Supercat. Thanks for playing

luckily we didn't see that kind of result with both the brain and the re amemiya catalyzers :D

Wow there is a lot of crying in here. Shit.

Thanks for the dyno^^^^ Im thinking about going to pick one up this weekend.

is it ok to install the rp supercat and the agency power cat back? what is gonna be the best cat back with the rp supercat?

hey i have a sp2,

i was wondering how much louder is the midpipe compared to a high flow cat?

and if it is alot louder than high flow would it sound like a high flow if u put the resonator on it or will it sound just normal like ur exhaust and u only get the gains?

thanks,
jake

Yeah, im trying to get a rp supercat and work it with my stock exhaust. Does those 2 work good together? I wonder if it will sound good together and loud haha. i went to this site http://rx7.com/store/rx8/rx8exhaust.html but i do not know if this is the right one can anyone check for me? But for now i think i am going to go with just the RP supercat and later get some exhausts and others hehe =D.

There are other catalyzers that don't gut that easily.
You should try them even if the cost is definitely higher. There is the brain cat that respects FIA standards (www.brainkat.net i think) but i gutted that as well, now i'm using the re amemiya one and it is an excellent product!

I just order the re-amemyia catalyzer so iam waiting for the results

< shot flames w/ supercat


also threw CEL with supercat lol

So i guess it comes down to either the RP supercat or the re amemiya, i wonder what im going to get. Which one is generally louder?

The RP guts, the re amemiya doesn't

So the RP is louder im guessing? i have no idea what guts mean and also the term cel is being used a lot would be cool if i knew what those meant. Also i dont know if a turboxs exhaust and the turboxs race pipe will be better together (heard its loud) or just get the rp supercat and stick with stock exhaust. any helpful hints? I want to go for sound and loudness haha but no midpipe!

the rp will be melt in a short time, the re amemiya won't

alright thanks guys i think i know now hehe =D. I think i should just get the R.E. Amemiya SUS SPORTS CATALYZER in the long run. Does anyone know a website where i can purchase this? I can never seem to find the site to purchase the products lol. Hopefully this will sound good with the stock exhaust and loud hehe:)

rhdjapan.com and japanparts.com have that item i think. you have a 10% discount on japanparts, read their seller section to know how to get it :)

the rp will be melt in a short time, the re amemiya won't

:bsflag:

I have many dyno runs, track days, and hard miles on mine with no trouble. I am also running the RB street flash.

There are many cases where they didn't last much, especially here. Same for brain catalyzers.
I changed a lot of catalyzers before finding a long lasting one =)

There was a problem with the early design (round style). These new ones are much better and some guys are running them on FI applications with no trouble. They are by no means prone to failure in genreal and for the price you cant beat them. RP even warranties them.

I trust you if you say so, but i would suggest the other one anyway. It may cost more but when you hold it in your hands you easily understand why.
I tried many different catalyzers and made Brain change their design after several failures as well, but in the end i bought that one anyway

I order from here:

http://www.worksconcepts.com/index.php?main_page=

So basically what this high flow cat does is makes it louder correct?

so what are the actual specs of the RE high flow cat?

and some info on the brain cats.. more is more.

beers :beer:

Sure,
They are some pretty well made catalyzers that come both in 200cpsi (street use) or 100cpsi, the latter following FIA standards.
The problem is that the first series had a small diameter and the high temperatures melted the welding points of the catalyzer itself to it's "cover".
Now they increased the diameter but in this way there's a slight power loss compared to the previous model.
They come already welded to the midpipe but the weldings are not well made in some cases, of the same batch ordered 3 out of 5 had to be rewelded after less than 10.000km.

I think that TeamRX8 tried them as well, he might continue with his impressions since he changed manufacturer too.
The website is brainkat.net anyway but it's in italian so here's the mail for a direct contact: brainkat@libero.it

hope this helps
