whats the problem with the random tech high flow cat? i see people posting stuff like "RT cat hater #1" and stuff, but what exactly is making these people hate these cats? i dont have one, but i was interested in getting one and i was under the impressed that it is a good quality problem?

someone please let me know! thanks guys

 

I heard it causes a CEL?? Not in 100% of owners I think....

 

It develops a very annoying rattle over time.

 

wtf is a CEL??

 

CEL= Check Engine Light. And i have heard about the rattle too.

 

wtf is a CEL??

 

does anyone have 1st hand experience with the RT cat that knows exactly what happens with it?

i appreciate all the suggestions from u guys but i need to know for a fact what happens to the damn thing!

and also, if you didnt get the RT cat, what could u get in place of it to improve performance?

 

Just to let you know Carsound and Warpspeed performance both make cats for maxima's. They are both cheaper than the RT also at around $100. I am sure you will get some replys from people who own/have owned the RT cat if you wait a little while. Why do you want a cat anyway? they give barly any gains.

 

I have had mine for 2 years now. The cover for it has like 4 welds
and one of the welds broke a was making a rattle noise, but I took
the cover off and no problem since then.
They have my vote.

 

Yup it sucks. Overpriced and basically a POS. Shelled out on me in 3 weeks.

 

the ceramic waffle (aka a filter) inside the cat comes loose and begins to rattle at certain rpms.. and then rattles all the time...





good thing i got my money back...

 

I have a racing straight pipe! You get some good horsepower.

 

that is what i replaced my cat with.. it makes "bees in the can" louder.. and there was minimal gains.

 

Really? Mine makes no noise!I got it from Custommaxima for 79 bucks.

 

that noise is not from the straight pipe.. it is from the aftermarket y pipe..


and i got mine cheaper.. and it is the same thing as yours... and not from custom maxima

 

I had a problem with those 4 spot welds too but took off the little shield and all better. Then the RT failed me after 17K miles causing lots of emission headaches. RT swapped it under warranty for just shipping. Another 18K on it right now and all is well. Dyno coming with 60 days of RT vs gutted OEM cat...

 

i got the hiflow metallic substrate cat from warpspeed and i like it.
