Stock 5.9L exhaust and cat size?
 
Hey guys...I searched, and cant find a straight answer...what is the size of my exhaust pipe going in and out of my cat...then in to my muffler, and out to the tailpipe? Some say 2.25, some say 2.5, some say 2.75. I just need to know because I need a new cat and muffler, and need to know the sizes to get on each.
Thanks for the help! :thumbsup:

Kolak would know that exactly. Pretty sure the tailpipe from the muffler on is 2.75"

I measured mine. It's smaller than 3 but larger than 2.5 so 2.75 sounds right.

Cool...thanks a lot!
So that is all the way from into the cat, out the cat into the muffler, and out to the tailpipe right?

No just from the muffler to the tail.
