Sigh,
Alright, plese don't take this personally and I am really not trying to offend you but, here goes:
First there are only 2 questions you posed:
and
Now, given the premise stated here:
The first question is completely contradictory unless you provide a reason you want to keep the stock cats.
Next, your premise stated as such:
Negates any reason for requiring LT's or an Off Road X/H unless you are looking for sound above all else or as you stated "just wantng to get rid of cats".
Now some logical reasoning if you please. The rich condition usually following the installation of a blower does have negative effects on Cats and many here have fallen victim to broken and plugged cats which may lead to engine damage. So, is it in your best interest to go catless with a blower? Most likely. But that still does not solve the reasoning behind wanting LT's. As you yourself stated (again for clarification purposes):
LT's are a useless mod for yourself unless you have some other reason you have not provided. SO to answer you final question then:
Given what you have stated, no, there is no reason for LT's and, yes, just an Off Road X/H may provide cheap insurance against a possible plugged cat/blown motor.
Ohh and I think my reading comprehension is just fine tyvm.
