I cut my stock cat off because it cloged and now want to know which one to get. I found one that is called a flowmonster on ebay. Does anyone know about these? How about car-sound?

 

Carsound are good. I bought a Catco myself. Can't complain about it at all.

Show me a cat that flows more than 450cfm and sells for less than $75!! I have yet to find one other than the Pypes. These are so compact that they will even fit onto both sides of an ORY.

 

I agree on the pypes. I went and did alot of search for a good high flowing cat and could not find anything better either for the price of the pypes. I got the pypes for 71.90 shipped. Thanks for the advice.

 

The metallic substrait cats flow the best, but they're not cheap. Well, there are some on ebay, but I know nothing of them.

The problem with the cheaper cats is that they coat with less of the catalyst to keep costs down. So in essence, they don't work as well.

 

Might do a search from Hot Rod Mag.They tested about 8 cats,and Catco flowed the best.(This was a few years back though).My02.

 

A few years back they didn't have the mettalic substait.

 

I did a search for matallic substraights,wow,big difference in the flow charts.What vendors here sell these?Many thanks Greed4Speed.

 

Anyone that carries Magnaflow should be able to get them.

 

do you need to pass emissions? an ory would be much cheaper..
