What size is the pipe, Im needing to replace my cats, with pipe of course.

IIRC its 2.25?

Also, are all the truck exhaust manifolds the same? minus the early EGR crap.

The Y pipe I made up 2 years ago, seems to be fitting like *** for some reason, so im fixing to remake it. I would swear one of the manifolds is different, but Hell I dunno.

 

Nobody knows?

 

Buy 2.5 and just fill in the excess with weld

 

Im pretty sure its 2.25, Ive done this before, I just dont wanna drive to the barn and cut a cat off and measure etc..
