hey,
i have a 2001 ranger 3.0 v6. i was curious as to what the stock exhaust size is. i also am going to make my own exhaust (40 series si/do dumped before axle) and i want to unbolt the stock exhaust system so i can put it on later if i want to. i was wondering what would i need to buy so that i can bolt a new pipe right one. i was thinking of buying the oem cat-muffler piece from advanced auto for $45. what do you guys think i should do?
thanks alot,
dillont

 

my stock exhaust on my 4.0 is 2.5 inches.

 

so your wanting one you can remove at the flange and bolt up?

 

No, it is not. Its 2.25....

 

I thought 4.0s were 2.5 and 3.0s were 2.25.

 

^^no.

On my 01 4.0L.......last cat to coupler is 2.5, after coupler is 2.0, after muff is 2.0, tip is enlarged to 2.25. I think i've seen 04+ with the tip enlarged to 2.5. Don't know for surethough. That's on a 4.0L, remember.



You could just go to a junkyard or check out craigslist and hack off one of those couplers to the muffler, and use that as a starting point. Should be 2" is what's needed.

 

Yep thats what I just found searching around in a old thread.

 

newbie.



Should have said.......they may have changed things around a little....like tail pipe size and the like. And with engine differences. That's why I put the year and engine size.
