Does anyone knows if there is a high flow cat for our cars yet?
I have a CAI and Header and hear that the cat is a big choke for airflow.

Thanks

You can have the stock cat cut out and replace it with a Magnaflow or Random Technology Hi-Flow universal.

Of course you dont get the benefit of a custom tuned cat w\ an engine pipe. Is not a bolt on, and would require welds.

 

i saw something on ebay, i think its called the fat cat? anyone know if thats any good?

 

Don't waste your time on those cat they sell on ebay. 99.9% of them are simply straight through resonators.

 

ther eis no such thing as a tuned cat is my understanding either they pollute or they dont lol..some more than others. the more pollution the better your performance is lol its your choice

 

You will find that most cats that are sold for a specific car are street legal, dont set off engine lights but still give great performance. It would be hit or miss with a universal.

 

thats true but they still arent tuned =)

 

No tuned cat, just better flow. The best flow cat is CarSound but most likely require flanges to be welded on both ends for you particular car. However, being street legal is one thing, it's not emission legal (I guess depends on your state/country) to replace a factory functioning cat with an aftermarket version. Many people had done it (myself included), but just don't get caught doing it. Major fine.
