I go to this shop to see about gettin a high flow cat on my truck with Flows and he tells me that my truck already has a high flow cat cause the trucks 96' and over come with high flow cats? anyone else hear this before?

 

I heard there are different oem cats. Some have a brick, and some have pebbles. One of them is the same design and as effecient as the aftermarket hi-po ones. I'm not sure which one.
There's still an issue with inlet/outlet tube size of the cat. If you have a larger pipe from a new exhaust then the cat tube is most likely smaller.

 

what year truck you have? most newer rangers do come with higher flowing cats. and an upgrade wouldnt be noticable unless you were boosted.

 

i got a 2000 3.0 2wd trailhead edition

 

whats a trail head edition?

 

like an fx4

 

no trail head is like an edge. it was a sport version, with torsion bars and it was 2wd

 

Most if not all cats are high flowing on vehicles made over the last few years. Cats aren't like they used to be any more, when they significantly restricted flow.

 

Idk, my friend told me his brother has a 01 ranger with the little leaf sticker and said that he had 5 cats... my truck has the leaf, so i guess i have 5 cats aswell... they better be something lol who needs 5 cats.

 

mine has the little leaf thing too.. i think that just means it will take ethenal fuel tho (shrug) i dunno

 

The leaf just means your vehicle is flex fuel (Allowing you to run E85).

 

so i dont have 5 cats?

 

you hafta figure that out yourself. The leaf has nothin to do with amount of cats, it means your vehicle runs on flex fuel.

 

you might.... i think i only have 3 and im flex...

 

idk theres only two packs of em, but my friend cut off my exhaust tonight so it sounds nice lol my gibson is coming in sometime next week

 

i have the high flow ones

 

alright thx for all the help, i think im just gunna keep my stock cat and just run my exhaust from the cat back and mayb throw on an air intake and possibly sum headers

 

Correcto! 3 is the magic number!

 

There are 3 or 4 of them (I don't remember how many mine has).

The first 2 are pre-heaters that heat up the exhaust for the CAT...the big one before the muffler is the actual CAT.
