I have a '95, 4.9 and want to get a high-flow cat. Anyone have one they recommend? Dynomax, Catco, Magnaflow??

Also, I am running Flowmaster 40 series, I'm looking for the best sound (deep rumble) anyone with the same setup who has a high-flow?

Thx

are you eliminating both cats and getting 1 new hi-flow? or just changing the last cat? if you do that then get a magnaflow hi-flow than a 3 1/2" tip on the end of your system...... youll notice a big change

I run a Random Technologies hi flow on mine with a Flowmaster 40, it rumbles good.

I'd like to replace both cats. I figure that gives the best sound. Or is it better to do just the last one?

ford5.8,

I saw in another post of yours you got your CATCO for $35, where did you get it from? Is it still available somewhere for that price

is there any way to tell if your cat is bad? if i might replace my cats with a catco 1 from ebay would i need to buy 2 to replace bolth of mine, or will one do the job

carsound makes the best cats. Catco does not.

Check the universals out on ebay and buy whatever size your pipe is.

I put one on my fathers dodge caravan that had a clogged cat and noticed better performance.

If you have 2 cats in a row one should replace them both, the one is a precat..

How are you determining that carsound is a better cat?

I've heard that they are both good, along with Random Technologies.

Anybody know any numbers for a cheap, but good, high flow cat for a 1995 4.9 inline six? I want to replace both my cats with one highflow so that I don't have the restiction, and get more performance.
