What is stock exhaust size on a 1992 f-150 with the 5.8 liter v8

 

That reminds me, I am thinking about changing from the single to dual exahusts on my 4X4 F150.

What is the down side of doing this?

Thanks

Yup I believe its 2.25" off the coverter and going to either a single 2.5" or dual 2.25" depending on what your truck came with from the factory. Mine had dual 2.25" tailpipes.

 

why would you not go for duals.you got the motor you should
not waste the sound.I have a 90 ford f-150 2 wheel drive with
a 302 in it i run 2"true duals with cherry bombs on it . And if i had
anything with a V8 in it would have duals on it. I love the sound,the looks of it coming out under the bumper. I think it would be well worth it going for duals. Are you going to buy them
or get some one to weld them up or what?

One reason I don't run duals-If you go offroad you will crush them eventually. There are more clearance issues and a single exhaust can flow and sound just like a dual can. It's just an appearance/personall preference thing.

Thanks for the reply. I appreciate the help, moose94 and akford351.

It "can", but it has to be substantially larger.

I think you have to run like a single 3" to equal dual 2.5"?

I don't really know how that works, so don't quote me on it, but you make a good point.

 

if i have an 89 with a 302 is it required to run with cats?

or does it vary from county to county?

 

its a federal law that you have to have cats.

it depends on your state though if you have emissions testing that says whether or not you can go without cats.
