Is RP Supercat still the best high flow cat?
I'm currently looking for highflow cat that doesn't throw CEL and last a long time, and I know that RP supercat is the best option for a awhile and just wondering if it is still the best out there compare to all the new high flow cat that has been introduced in the market. Currently I still have the stock header, cat & MS dual exhaust cat-back. I know Access Port will eliminate the CEL but unfortunately it is not an option for me right now.
|
i've had my RP Supercat on my car for almost a year now. I like it alot. havent had a single problem and never threw a CEL.
|
RP is a great readily-available option. Best? That's a tough one.
I ran my RP supercat for about 16,000. Pulled it off yesterday....dead. LOVED the sound it made, if I had it to do all over again, I'd still buy it. |

my car sounds SO quiet with the OEM cat. :(
|
Thx for the response, guys. How about the new Exoticspeed high-flow cat and those sport/metal catalyzer listed on Japanparts.com?
|
the HKS catalyzer is very tempting.

kenny: yup, on my list of things to do tomorrow. Thanks. :)
why would the Exoticspeed flow better? Aren't they both 200? |

I think you will see a common denominator contributing to failure.:eyetwitch
Just give it time. |
Now I really have to re-consider my options.
|
kenny: hinting at the AP? ;)
|
No, there have been several reported failures before the AP was out.
That's why I'm still waiting. I have not seen sustainable reliability. If you ask TeamRX8 he will say don't buy it. |
True, the early models failed prematurely. I think after they switched to the Bonez (sp?) cat, the reliability seems to have gotten better.
The AP will only diminish the Cats much quicker as Mazda's last few reflashes have RICHENED the fuel mixtures in an attempt to cool down the OEM cat and extending it's lifespan. Leaning out the AFR's is going to cook them up. How long they will last with leaned AFR's over rich AFR's is a question that we don't quite have an answer to. (too many other variables) Razz: if you cook yours before the 80k mark, just uninstall the AP and have the dealership replace. :) Team is partial to the European Cat (?) that he ran a while back, seemed to perform very well and held up to abuse at the track. (much pricier then RP) and I think it's JUST the 'cat' so you need to buy the right size and get it welded in. |
I have the RB Street Flash and have been quite happy with the tune.
It is designed keep the cat from exceeding critical temperature and I made over 200WHP with it. I think in my application the Supercat will hold up fine and I don't have to deal with that awful catless smell. :eyetwitch |
My supercat failed around 20,000 or so miles... it was the original design and they sent me a brand new one with the better design for free - no questions even asked. Supposedly they have had much better luck with this version. Also, many failures can be contributed to flooding and bad ignition systems...
|
i had a rp high flow and it crapped out within a year. no flooding, no ap, just normal everyday driving. if anyone wants it i'll get rid of it cheap. racing beat is the best way to go hands down. yes its louder (for now until their resonated version is released) but far better quality.
