I'm not the gearhead most of yall seem to be, but I need to replace the cat, muffler and tailpipes in my '90 Bronc with a 300.
Trouble is, I see so many different types out there, I'm having trouble knowing what to get! I guess I just need to know what size inlet to get, anywhere from 2-3 I guess.
Little help?

I'm so confused here... The cat has two pipes going into it, and all the ones I can find around here have only one inlet. Further, all the ones with 2" inlets have a maximum engine size of 4.0L, and mine's a 4.9.
Geez, all I need to do is pass inspection!

I guess I just need a thorough lesson in how the exhaust system works. I see round mufflers, oval mufflers, single and dual chamber mufflers, dual and single outlet mufflers, and about a zillion types of cats, all of which range in price from 50 to 200 bucks.
I'm pretty lost.

So I have a '91 w/351 and it had two cat's on it. It wouldn't pass emissions about a month ago. I got a complete exhaust system all the way back from the manifold and they replaced the 2 cats with one. The trick that the shop did was make a
y-pipe that takes the two pipes from each manifold in but only has one going out. Then they put the one going out to the cat.
So I guess, on my truck I have a cat that has only one inlet. Also, the guy at the shop told me the usual size is a 2 1/4 inch.
