RP supercat
 

Just a few questions before I decide to spend my money on it. I tried searching and probably searched for the wrong thing cause these are simple questions I'm sure have been asked but I didnt find the answer, so: on the RP site it says the supercat is for off-road use only which I assume to be becaue of noise? is there any other problems or reasons it should only be off-road? not too concerned because it says it is street legal though. My other question is: I saw in a thread about the supercat someone asking if there were fitting issues with the RB exhaust and never saw an answer to the question. is there anything to it? or should it fit fine? any responces are appreciated, Thanks :wavey:

supercat is fine for street. it even passes smog still. if you get a hanger put on the supercat then there will be no fitting issues. i have the supercat w/ hanger welded + the rb exhaust.

It will not have any issues with fitment on any exhaust that can be fitted to the stock cat.

its off road only because its not CARB certified, but since you don't live in california it doesn't matter since it will pass a sniffer test and does not cause a CEL

Did they send it with hanger welded or did you have it added during install?

i had one welded on during the install. as far as i know at the moment. RP isn't offering the hangers.

Thanks for all the responses. Where exactly do you have a hanger welded on? I dont know how to weld or know where I'd have that done so I'd definitely need to figure out where I could have that done.

what you can do is install it, and take your car to a muffler shop and tell them you want a hanger installed. they'll lift your car up and put the hanger in and weld it. way cheaper than having them install the whole thing too.

Same with me, no issues.

Thats what I did, they charged me $17 at Jensen Auto.

yea... i didn't do that... lol i had them install it all for me and i felt ripped off. haha. damn deedubb said it wasnt guna cost all that much.

is it just not secure enough without that hanger? what problems would/could I have without the hanger?

actually. some haven't had any problems without a hanger, but i didn't want to take that chance. most problems people had were rattling because there was no hanger.

9,000 + miles without a hangar and no problems here. RP supercat is an outstanding product. If you have any questions, call them and speak to Chris. He's very knowledgeable and responsive to all questions.

I have that cat with the stock exahust, and I got that weird vibrating as I didn't have the extra hanger. You have to solutions, one, get a hanger installed in the factory location, or two, what I did, remove the two chasis braces along the exahust tunnel, which really don't do anything.

I'm waiting for the standalone hanger to come out from RP, and then I'll install it. If you want to check to see if this is your issue, remove the two braces from under the car and see if you still hear the noise.

I have a stock exhaust with RP super-cat and have no vibrations or cels...Granted I only put it on over labor day weekend. Lovin it so far! :rock:

do you guys really feel any difference in having a "super-cat"

I'm sure that questions been asked before, but to me it would make more sense just to remove the cat and have pipe only. I know it's illegal, but lots of people do illegal things...

yes,

i have something close.. but big change.... and as to no cat ... did it. not something i would deal with day to day..


beers :beer:

I have no hanger installed and no rattle. It is not much louder than it was before, just a bit angrier. I have had a racing beat exhaust installed since it came out. All and all I am happy with the purchase.

I could see a nice blue glow coming from his exhaust when he shifted. :)

I'm thinking of getting it but... I am wondering if its legal to have it installed. I live in California so i'm kinda concerned.

i have mine about a year now... no problems and still no hanger

Those braces are important for preventing chassis twist & flex, highly recommend that you reinstall them.

It is Illegal to remove a perfectly good operating cat in CA. A lot of Muffler shops will tell you this when you ask them to put on a high flow cat or do anything with the cat for that matter.. But they would still do the work for you maybe on a "side job" basis. When you get a smog test as long as it passes the snuffer you would be ok.. The normally do not look at the cat unless your car is all modified and it does not past the snuffer for other reasons.

im not from CA - but even here in texas, the mazda techs didnt phsysically look at my CAT on the "big" recall i just went thru... when i told them i had a custom SuperCAT they flipped out and were just weird/stupid.

the RP superCaT is highly reccommended.

Hay Guys.. I just got my RP Supercat on Monday.. I didnt put it on as soon as I got it like I wanted to because I had the BIG recall thing.. Yesterday morning I took it in to Browning Mazda in Cerritos CA. They told me it was going to take a Day or two... I was like AUG!!... But oh well... They said they have a rental car for me... I went next door to the Dodge Dealer they had an Enterprise rental car place in the office... The Mazda Dealer paid for it but they gave me a dam KIA Spetra... AGGG... I asked the person helping me if it can go on the freeway and she told me it could... (she was right.. It could.. but she failed to mention Only in the slow lain." Any way Mazda called me arround 4 pm and said my car was ready... I picked it up. Everything was ok with my car... Only needed on leading spark plug changed. and the reflash.. that was it...

OK.. now with the RP SUPERCAT STUFF..

Like a dummy... I sprayed the cat with "high Tem spray paint" ....... I must say.. DO NOT DO THIS!! It does look very nice after I did it.. but when I put it on.. lastnight and drove it... IT was smoking and smelled bad... I guess the paint was not that good to take the heat.. But... anyhow... The car drove very nice.. felt like it flowed better. I havent got to take it to very high RPMs. but as I went faster It felt better and better.. The only thing I don't like is the noise.. For me.. I have a Greddy exhaust and it is LOUD. But not raspy at all... More of a loud rotary sound.. Kinda nice sounding in a way... But for the most part.. after the paint burned off it is a Great part and Im happy.. I may still get a Dynomax Bullet put in for the sound but I will drive it more to see how it is going.

Very nice review. I also have a Greddy exahust and now I can expect what kind of noise it will produce.

Well, I should get mine in tomorrow or friday... I just moved for college and kinda screwed up the address when I ordered... put my old street address + new city/zip code :doh: but I should be able to fix it tomorrow I think (hope). I have RB exhaust and intake, I'll let you all know how it is when I get mine in and installed.

does it void the warrinty? while im asking, does my borla exhaust void the warrenty? how bout an intake like aem cai, or k&n short ram? i know this is kinda off topic but if someone could answer that would be great

All of that can void your warrenty.

kinda, in most cases it voids warranty on that part alone. the exhaust should be exhaust warranty only. not too sure about intakes though.

are you able to hear the supercat when you are on the highway or cruising or is it just when on the gas??? i know that with my greddy exhaust its pretty quiet on the highway and i'm just wondering if this will be the same. thanks

I finally had to go with a cat and obviously since it's an RP Supercat I had to have it. I also have a Hymee cat back. It was too loud for my taste when I put it on. I'm an old fart so it might be just my taste. I had a resonator welded in but there was little space left for much of one. It is kinda nice when I want to show off but still a little over for me most of the time. I'm going to see if they can put a bigger resonator in the pipe further up. If not I can get along with it.

On the quality side it is a very nice part and I have no problem with it having RP on it. j/k ;) :rollingla
I have no idea what all the flack is about a hanger, seems just fine the way it is.
I have no rattle even with the added weight of the resonator.

I always thought you made the RP supercat, until some forum members posted Rotary Performance on one of the threads a long time ago

uHm..... just one dumb question.. after install a supercat does fire comes out of ur exhaust when u shift at high RPM? cuz... that's something i dont want.. LOL i live in CA and i dont wanna get pull over... it's a huge fine....

It does. Hack you can even get fire from the stock system if you try hard enough.

you have to really drive it hard if you want flames. but yes, it can happen even with stock.

Always wondered your take on the cat RP. :D:

does anybody have an answer to my question???? :scratchhe

If it is anything like the SR you should be able to hear it driving down the highway. If you have the resonator installed, it will be a little more subtle.

Deeper tone, more noise when letting off the gas. I have the Greddy and it gives a nice tone when shifting gears. Coupled with a blow off valve I am sure it will sound awesome.

Oh and more noise when stepping on the gas especially when going through an underpass. Quite a bit more growl. :evil_laug

You know that subtle boom sound when shifting? Magnify that by ten and you will have it. ;)

cool thanks for the response. and with the addition of the supercat that nice little boom at the shift should also come with some flame action :rock:

I don't hear the cat unless I'm on the throttle hard with the stock exhaust. Cruising around the RP is just as quiet as stock for me at either 40mph or 70mph

well i just ordered one last night so hopefully ill get it soon

I just got my supercat today but I was wondering what is the lone welded hex bolt there for? :Freak_ani

pics,
where is it..

beers :beer:

i have the supercat with sp2 exhaust and it is loud as hell!!! im not too fond of it and am now looking to switch to the hks legamax instead of the sp2. also i had the heat sheald, that comes welded on the cat, fall off wi=hile driving down the freeway the other day???

P.S the greddy sp2 and rp supercat combo will get flames to come out of the tips once its warmed up ....but i would recomend a set of earplugs,...haha

you need to answer this?

Here are those pics. I have an sp2 and now I am hearing sp2 combo with the supercat gets its very loud. Is it something I should worry about since I do live in CA? :Eyecrazy:
