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.
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.
