If you are not running some form of boost then 4" is overkill.

I want the magnaflow pn#12594 dual 3 inch in 4 inch out.. only have a 4 inch tail pipe. Im thinking of running a xpipe where the cats where. Also thinking of putting dynomax bullets to replace the cats that I already removed

i know you know this but stock trucks been running 3.5 for yrs now.....4" really isnt much larger and if you choke it up with smaller lead pipes then the muffler section wont matter as much

This is true however the selection of mufflers also goes to **** when you go to 4".

What gassers have factory 3.5?

Thats up for debate on '' the best sounding '' people like diff things.. I always liked bullets, dynamax sounds great but depending on where the muffler is it will have a hard brap to it.. Had dyna, then swapped to a big *** edelbrock diesel muffler.
