Upgrading exhaust while keeping the cat?
So my truck does not have the stock exhaust, its got a Magnaflow muffler with the stock size pipes and a single in dual out muffler which they then routed a pipe to behind each tire. This was done years ago and personally it never changed the sound a bit to me but anyways. I would like to keep my factory cat, i have no clue if its gutted or not i assume it hasnt been however. In Texas all you need it for is visual, but as far as the EPA is concerned its illegal to alter it in any way.
How do i check it to make sure it is not clogged?
What are the best options to keep it, the number of cat back systems are limited, is there a way to purchase a turbo back and integrate the cat in there without much trouble?
I would LOVE to do 5" exhaust and keep it dual like my current set up but the guy who did the current dual said it was a PITA to do this, and ive read that the in bed hitch messes up the ability to do duals. has anyone run into this and what did you do?
Since there is a price difference between the 4" and 5" versions of everything what are the main differences is there much extra sound with that 5" will i even get much sound by keeping the cat?
Adding this thought i just had, would it make sense to just order a turbo back system and get some Pipe size changers to fit in the Cat would that hurt it or would that work okay? I guess some pipe that was like a 3.5 one side and 5 on the other if i went 5" system?
