does anyone know the size of the stock exhaust where it goes into the muffler? Gonna pick up a cherrybomb glasspack tomorrow and need to know and my truck is at the garage so i cant see for myself. thanks!

 

i think 2.25 but dont qoute me on that maybe 2.5. i know someone know s

 

yeah i know its somewhere around there but i want to be sure. If in doubt i will just go with the 2.5 i guess, i'm just putting a turn down right on the glasspack anyway.

 

i would do 2.5 and get a fitting for it, to small it will sound flappy

 

yeah exactly i dont want to have to downsize the pipe for the muffler... i'll go with the 2.5

 

its 2.5 inlet and 3 exit on my truck

 

alright thanks buddy!

 

2000 was different that 1994.

I believe 94 was 2.5" pipe. Does it appear to neck down at all, or is the pipe straight? Dodge did not use a 2.25" pipe on the 2nd gen Ram in any year I am aware of.

Cut a 2.5 inch circle out of an old pizza box. hold it behind the pipe and see if you can make it disappear. If it did, you have 2.5 or bigger. If you can see a significant amount of hangover (depends on how accurate you cut) you have a smaller pipe.

 

On the 97's behind the cat housing is 2.5". Before the cat housing is 2.25".

IIRC, the change was 98 on the piping, correct?

 

I believe so, and in 2001, they went to 3" with 2.5 neckdowns at the cat and muffler so they could use up all the back stock, LOL.
