a simple muffler question...

[spencer2001]

so im looking at mufflers (magnaflow, cherry bomb, dynomax... typical things...) but how big should i get for my 2001 SR5 automatic 2WD with K&N cold air...
do i have 2.5" inlet or 2.25"?
and im probably just going to put a turn down pipe right out the back so does the back outlet size matter too much?

basically i need to know:

2.5" or 2.25" ?!?!
how long should i get too?
18" 24" etc etc...

I got the 2.25" Vortex. If you go this route there is only one option.

 

[spencer2001]

so 2.25" is what im looking for all or just for vortex?

You will want to look for 2.25" for all of them. I think I remember someone saying that they got 2.5", but I believe 2.25" is the correct size. If you are wanting to do a dual exhaust or something like that you will need to get a single in and dual out muffler.

I'm not sure about the lenghts of Flowmaster and Magaflow.
